Keep your business running: Sol-Ark 30K-3P-208V Commercial Inverter
Why You'll Love The Sol-Ark 30K-3P-208V Commercial Hybrid Inverter
-
Outages stop costing you money. 30kW of continuous three-phase power with 45kVA of surge keeps your operation running when the grid drops, so downtime doesn't quietly swallow a day's revenue.
-
Native 120/208V three-phase, with nothing to convert. It outputs the voltage your building already runs on, which keeps the installation simpler and the equipment count lower.
-
Works with the solar you have, or the solar you're planning. Up to 39kW of DC PV across four MPPTs plus 30kW of AC coupling means a retrofit is as straightforward as a new build.
-
Start at 30kW and scale to 300kW. Parallel up to 10 units as the business grows, all backed by Sol-Ark's standard 10-year warranty.
Your business, with the Sol-Ark 30K-3P-208V Commercial Hybrid Inverter
For a business, a power cut isn't an inconvenience. It's refrigeration at risk, production stopped, tills down and a day you don't get back.
The Sol-Ark 30K-3P-208V is built to make that somebody else's problem. It delivers 30kW of continuous 120/208V three-phase power with 45kVA of surge for 10 seconds — enough to restart the motors and compressors that stall lesser backup systems.
It earns its place on ordinary days too, turning your roof into a way of pulling down what you hand the utility rather than simply paying whatever the meter says.
The engineering is sized for commercial work throughout.
Four MPPTs take up to 39kW of DC solar across eight strings, and you can AC-couple a further 30kW — so an existing array doesn't need tearing out to add storage. Grid pass-through runs at 180A continuously, or 200A for up to ten minutes.
Batteries connect as a high-voltage lithium-ion bank rather than the 48V arrangement used on residential units: 300V or more nominal across a 160–500V range, with two battery inputs and BMS communication over dual CAN.
It's IP65 / NEMA 3R rated, operates from -40°C to 60°C, draws just 60W at idle and sits under 30 dB, so siting it is rarely the difficult part. Wi-Fi and LAN hardware are included, and the MySol-Ark platform gives you real-time monitoring and fleet management from anywhere.
The Sol-Ark 30K-3P-208V Commercial Hybrid Inverter in a nutshell:
-
30kW continuous three-phase at 120/208V — native output with 45kVA of surge for 10 seconds.
-
Four MPPTs, 39kW DC solar plus 30kW AC coupling — suits new arrays and retrofits alike.
-
High-voltage lithium-ion battery input — 300V or more nominal across two inputs.
-
Parallel up to 10 units — 30kW to 300kW as your energy needs grow.
