Manufacturers we specify

Solis has the range; the ranking is a separate question

Solis is the inverter and storage brand of Ginlong Technologies, ranked third in the world by 2024 PV inverter shipments and fifth in a separate scored manufacturer assessment for the first half of 2025. Neither of those is a bankability placing and we do not present them as one. What the brand does bring to a commercial roof is an unbroken three-phase string range from 30 kW to 150 kW, up to ten trackers on the larger machines, and a storage cabinet line that parallels a long way past a single unit.

A high-volume string-inverter house whose depth of range is the reason to specify it, and whose ranking claims need reading carefully.

Solis is the brand name of Ginlong Technologies, which has built string inverters since 2005 and now ships at a volume few makers match. For commercial solar above 50 kWp it gives us something genuinely useful and quite rare: a three-phase range with no gaps in it, so a 40 kW sub-array, a 125 kW roof and a 150 kW light-industrial array all sit on the same platform, the same monitoring and the same commissioning routine.

The storage line uses the same S6 hybrid platform, paired with cabinets that arrive with the conversion and the controls already inside them. What the brand does not have is a current bankability placing, and this page is careful to keep that separate from the rankings it does hold.

01 Bankability

Two rankings, and what neither of them measures

Solis is easy to over-claim, because it holds two prominent placings and both sound like financeability. Wood Mackenzie ranked Ginlong Solis third in the world for PV inverter shipments in 2024, and fifth in its scored manufacturer assessment for the first half of 2025, which weighs after-sales service, research spend, supply-chain stability and manufacturing experience rather than volume alone. The first measures how many units left the factory. The second measures manufacturer quality. Neither one tells a lender whether the warranty will be honoured in year twelve.

So the honest conclusion for a finance committee is a scale-and-documents conclusion. This is a long-running pure-play string maker with a very large installed base and a broad UK distribution position, whose commitments are evidenced by the issued warranty document for the specified model rather than by a survey result. We read the warranty term, the retained-capacity basis and the throughput limit off that document before contract, and where a funder wants a current independent bankability placing on the inverter we say plainly that Solis does not hold one.

  • Since 2005 Building string inverters one of the longer-running pure-play makers
  • 100 GW Cumulative inverter shipments passed in the first half of 2024
  • Fifth Scored manufacturer assessment, first half of 2025 weighs after-sales service, research spend and supply-chain stability
  • IEC 62619 Cell and battery safety standard verified against the certificate for the specified cabinet
02 The full range

One platform from a 30 kW sub-array to a 150 kW roof

Inverters

Three-phase string inverters across a continuous commercial band

A single family that covers a 30 kW plant-room feed and a 150 kW roof without changing platform, so the design settles on the size the array actually wants rather than the size the range happens to hold.

  • S5-GC30K
  • S6-GC3P(40-60)K
  • S6-GC(80-125)K
  • S6-GC3P(125-200)K
  • Solis-(80-110)K-5G-PRO
  • MPP trackers, S6-GC(80-125)K: Eight to ten
  • Maximum DC voltage: 1,100 V on the larger S6
  • Enclosure: IP66
  • Peak efficiency: Up to 98.8% on the 150 kW unit
  • Topology: Transformerless

The 5G PRO and the largest S6 machines are utility-weight units; on a small or heavily interrupted roof they are more inverter than the array can put to work.

Battery storage

All-in-one and packaged battery cabinets on the S6 hybrid platform

Behind-the-meter storage where the power conversion, the transfer switch and the energy management sit inside the cabinet with the cells, so there are fewer vendor interfaces to align on site and one controller deciding when to charge, hold and discharge. Every configuration in the range pairs a power rating with an energy figure, and the two are separate purchases: the power sets the size of the peak the store can cover, the energy sets how long it can hold it.

  • EverCore
  • PrimePower
  • EverCore configurations: 50 kW / 100 kWh, 60 kW / 120 kWh, 125 kW / 261 kWh
  • Duration at rated power: Two hours at each step, about 2.1 at 261 kWh
  • PrimePower master unit: 50 kW / 109 kWh, about 2.2 hours
  • Cell: 314 Ah LFP prismatic
  • Cooling: Air-cooled, no liquid coolant
  • Paralleled maximum: Around 1.25 MW and 15.66 MWh
  • Grid to off-grid transfer: Under 10 ms

The whole range sits at roughly two hours, so it is shaped for shaving a daily peak rather than for shifting a long evening block; a four-hour duty needs more cabinets than the power rating alone suggests. Air cooling also holds a wider cell temperature spread than a liquid-cooled block, which tells most where the duty is hard daily cycling in a warm, enclosed plant area.

Datasheet figures only. We publish no price, and the exact model is confirmed against the design and the current datasheet before order.

03 Datasheet

What the larger S6 machine actually carries

These are the numbers that decide whether one Solis machine can take a whole commercial roof. They are taken from the S6 datasheets and are confirmable.

  • Ten Independent MPP trackers on the S6-GC(80-125)K
  • 1,100 V Maximum DC voltage longer strings, fewer parallel runs
  • IP66 Enclosure rating sits on an exposed roof without a weather cabinet
04 Tracker strategy

Grouping strings by orientation on a split roof Ten trackers is a layout tool, and it changes what the roof is allowed to look like.

A commercial roof rarely offers one clean orientation. There is an east bank over the older bay, a south bank over the newer one, a lower pitch behind a parapet and a stretch shaded by plant until mid-morning. With three or four trackers those groups have to be forced together, and the weakest one drags the input it shares. With eight to ten, each group tracks its own maximum power point.

The practical results are two. Morning and afternoon yield stop competing, because the east bank is allowed to peak early without pulling the south bank off its point. And a soiled, shaded or damaged section drops only its own tracker rather than the whole machine, which turns a whole-array fault into a partial one and shows up in the monitoring as a named group rather than an unexplained shortfall.

This is a grouping tool and not a shading cure. Where the obstruction is fine-grained, a flue here and a handrail there across many modules, no tracker count recovers what module-level electronics would, and we say so and price the alternative. Where the roof is simply split into large coherent areas, which is most commercial stock, the tracker count does the work at a fraction of the DC-side hardware.

05 Storage

Storage that arrives as one cabinet EverCore puts the conversion, the transfer switch and the energy management inside the enclosure with the cells.

The commercial storage line is built on the same S6 three-phase hybrid platform as the inverters, in roughly the 30 to 125 kW band, paired with battery cabinets holding 314 Ah lithium iron phosphate cells. EverCore is the all-in-one: fewer separate boxes on the pad, fewer interfaces to coordinate between vendors and one controller deciding when to charge, hold and discharge against your tariff.

Capacity comes in three set configurations, from 50 kW with 100 kWh up to 125 kW with 261 kWh, and cabinets parallel to a system of around 1.25 MW and 15.66 MWh. So one product line covers a single cabinet beside a roof array and a multi-cabinet industrial store, which keeps the warranty conversation and the architecture the same as a site grows.

Two engineering details matter on a working site. The transfer from on-grid to off-grid runs in under 10 ms, which is inside the ride-through of most process control gear, and the cabinet delivers up to 1.6 times rated output for 200 ms off-grid so a heavy motor start does not trip the store. The system is air-cooled, with no liquid circuit to maintain across the asset life.

06 Cabinet choice

EverCore against PrimePower

Both are built around the S6 three-phase hybrid. The difference is how much of the system arrives already assembled, and that decides the install as much as the electrical design does.

Recommended Integrated

EverCore, the all-in-one cabinet

Power conversion, inverter, static transfer switch and energy management integrated alongside the battery in a single enclosure.

  • Three set configurations from 50 kW with 100 kWh to 125 kW with 261 kWh
  • Every step holds about two hours at its rated power
  • Cabinets paralleled to around 1.25 MW and 15.66 MWh
  • Fewer connection points to coordinate on site
  • DC or AC coupled to the array, decided per site
Packaged

PrimePower with high-voltage stacks

The S6 hybrid paired with separate high-voltage battery stacks rather than a single integrated cabinet.

  • The master unit is specified at 50 kW and 109 kWh, about 2.2 hours
  • Capacity built from stacks rather than fixed cabinet steps
  • Suits a plant area where one large enclosure will not fit
  • Same S6 platform and the same monitoring

More separate components to align at commissioning than the integrated route, and the master and slave designations are confirmed with the manufacturer before a multi-cabinet layout is drawn.

Capacity is sized against your half-hourly consumption before either option is named, and the ratings and warranty come from the current datasheet for the exact model.

Solis earns its place on breadth and on tracker count. It loses it on two specific things, and both are worth saying before a design starts rather than after.

08 Honest placement

Where the Solis range answers the roof

Specify

Where it fits

  • Large roofs carried across several pitches, where eight to ten trackers on one machine group the strings by orientation.
  • Schemes that want one inverter platform from a 30 kW sub-array up to a 150 kW roof.
  • Behind-the-meter storage where an all-in-one cabinet removes the interfaces between separate vendors.
  • Ground-mount and large-roof string duty, where the 5G PRO platform is built for the job.
Specify something else

Where it does not

  • Financed schemes where the funder asks for a current independent inverter-bankability placing.
  • Heavily shaded or cluttered roofs, where module-level electronics recover more than any tracker count will.
  • A store whose growth path runs well past a megawatt, where the cabinet parallel ceiling becomes the design limit.
  • Hard daily cycling in a warm enclosed plant room, where a liquid-cooled cabinet holds the cells tighter than an air-cooled one.
09 FAQ

Solis on a commercial roof: common questions

Solis is an established global maker by scale rather than a bankability leader, and we keep the two apart. Wood Mackenzie ranked it third worldwide for PV inverter shipments in 2024 and fifth in its scored manufacturer assessment for the first half of 2025, which weighs after-sales service, research spend and supply-chain stability. Both measure the manufacturer, not financeability. The most recent independent bankability placing we hold dates from 2019 and is too old to quote, and the current inverter-bankability survey is led by another maker. Where a financier requires a present-day placing, we confirm the position for the exact model or put a different maker forward.

The S6-GC(80-125)K models carry between eight and ten independent maximum power point trackers. On a roof split across several pitches, orientations or shading zones, that lets each coherent group of strings track separately, so the east bank is not pulled onto the same input as the south bank and a soiled section drops only its own tracker. It is a grouping tool for large distinct areas rather than an answer to fine-grained shading.

Both are Solis commercial storage built around the S6 three-phase hybrid inverter. EverCore is the all-in-one cabinet, with the conversion, the transfer switch and the energy management integrated alongside the battery, which leaves fewer separate boxes and connection points to coordinate on site. PrimePower is the packaged alternative, pairing the S6 hybrid with high-voltage battery stacks, which suits a plant area that cannot take one large enclosure. We choose between them from the site and the load rather than by default.

Each cabinet size comes in four versions and the environment picks one. NV is the standard build; NV-C5 adds the C5 enclosure grade, C5 being a category on the ISO 9223 atmospheric corrosivity scale; NV-PRO adds a lithium-ion detector, an explosion relief board and two explosion-proof exhaust valves; NV-C5-PRO carries both. That is the same corrosivity category the fastener and coating schedule for the mounting system is written from, so the array and the cabinet are graded from one assessment of the air the site actually has, as set out on our page for coastal and exposed sites. On a salt-laden yard the corrosion grade is the specification, and where an insurer or the fire strategy calls for detection and relief the PRO build is. We set the version from the survey and the fire-safety assessment and record the reasoning in the design.

We do. As the specifying and installing contractor we hold the monitoring access for the inverters and the storage, handle warranty claims and correspondence with your network operator, and keep the as-built records a financier or facilities team needs across the life of the asset. A fault routes through us rather than a manufacturer call centre, and the warranty term for each specified model is confirmed in writing before contract and registered at commissioning.

There is no published price for any of this equipment. The inverter model, the machine count, the cabinet count and the DC to AC ratio all come out of the modelled design for your roof and your half-hourly load, so a catalogue figure for a box would not describe your scheme. The proposal quotes one scope and one figure, with the model, power, phase and tracker count named openly.
