Commercial energy at scale: Sol-Ark 60K-3P-480V Inverter
-
Keep critical operations running. 60kW of continuous three-phase power with 90kVA of surge for 10 seconds keeps production, refrigeration and essential systems live through a grid outage, so downtime stops eating into revenue.
-
Attack your biggest utility line item. Peak shaving trims the demand charges that dominate commercial bills, and the platform can participate in grid-services programs for additional revenue.
-
Native 277/480V three-phase, ready for your building. It outputs the voltage commercial sites already run on — 4-wire Wye or 3-wire Delta — which keeps installation simpler and the equipment count down.
-
Built to scale with the business. Parallel up to 10 inverters for 600kW of power, with up to 16 batteries per inverter and storage that scales to 9.6 MWh — all on Sol-Ark's standard 10-year warranty.
Your business, with the Sol-Ark 60K-3P-480V Commercial Hybrid Inverter
For a commercial operation, two energy problems quietly cost the most. The demand charge that lands every month whether you notice it or not, and the outage that stops the business cold.
The Sol-Ark 60K-3P-480V is built to take on both. Peak shaving pulls down the demand peaks that drive your bill, while 60kW of continuous 277/480V three-phase power — with 90kVA of surge for 10 seconds — keeps your operation running when the grid doesn't.
And it's designed to grow rather than be replaced. Parallel up to 10 units for 600kW of power, add up to 16 batteries per inverter, and scale storage to 9.6 MWh as the site's needs expand.
The engineering is sized for serious commercial and industrial work.
Four MPPTs take up to 78kW of DC solar across an unusually wide 150–850V range, with a 1,000V maximum input that suits long commercial strings. You can AC-couple a further 60kW, so an existing array integrates rather than gets scrapped. Grid pass-through runs at 180A continuously, or 200A for up to ten minutes.
Batteries connect as a high-voltage lithium-ion bank — 600V or more nominal across a 160–700V range, with two inputs and BMS communication over triple CAN. Both AC and DC coupling are supported, so the 60K drops into new builds and retrofits alike.
It's IP65 / NEMA 3R rated, runs from -40°C to 60°C, draws just 60W at idle and sits under 30 dB at one metre. Wi-Fi and LAN hardware are included, and the MySol-Ark platform gives your team real-time monitoring and fleet management from anywhere.
The Sol-Ark 60K-3P-480V Commercial Hybrid Inverter in a nutshell:
-
60kW continuous three-phase at 277/480V — with 90kVA of surge for 10 seconds off-grid.
-
Up to 78kW DC solar across 4 MPPTs plus 60kW AC coupling — a 150–850V range for long commercial strings.
-
High-voltage lithium-ion battery input — 600V or more nominal, up to 16 batteries per inverter.
-
Scales to 600kW and 9.6 MWh — parallel up to 10 units as the site grows.

Sol-Ark 60K-3P-480V Commercial Hybrid Inverter documents and materials
Disclaimer: Potential energy savings and utility cost reductions depend on system size and configuration, energy usage, utility tariffs and demand charges, local regulations, weather conditions, available incentives and installer design. Actual savings and performance will vary.
The information on this page is provided for general guidance only and should not be taken as professional, electrical or medical advice. The Sol-Ark 60K-3P-480V is a high-voltage, three-phase, grid-interconnected commercial product weighing 176 lbs, and pairs with a high-voltage battery bank. It must be specified and installed by a suitably qualified and licensed electrical contractor in line with the manufacturer's installation manual and your local codes; commercial grid interconnection will normally require permits and a utility interconnection agreement. Every site is different, so if you have any doubt, please consult a qualified professional before purchasing or installing. Products are used at your own risk.
