Outdoor commercial energy storage: Sol-Ark L3-HVR-60 Battery Bank
Why You'll Love The Sol-Ark L3-HVR-60 Outdoor Battery Bank
-
61.44 kWh of storage that lives outside. 55.30 kWh usable of safe LiFePO4 in a weatherproof enclosure, purpose-built to pair with the Sol-Ark 30K-3P-208V inverter — no indoor floor space or battery room required.
-
Built for the elements. An IP55 (NEMA 3R) outdoor enclosure runs across a wide -20°C to 50°C range, so it keeps working through hard winters and hot summers alike.
-
Safety engineered in. Built-in module and cabinet fire suppression, plus UL 9540 and UL 9540a listings, make the system straightforward to permit and to site.
-
Scales as the site grows. Stack up to 6 cabinets per inverter and parallel up to 6 inverters — 180kW AC and 2.2 MWh of storage — all on a 10-year warranty.
Your business, with the Sol-Ark L3-HVR-60 Outdoor Battery Bank
Plenty of commercial sites want energy storage but don't have the room to give up for it. Floor space is revenue, and a fire-rated battery room is a project of its own.
The Sol-Ark L3-HVR-60 solves that by living outside. Paired with the Sol-Ark 30K-3P-208V inverter, it banks solar or off-peak energy through the day, shaves your peak-demand hours to trim the bill, and keeps critical loads running when the grid drops — all from a weatherproof cabinet on a pad rather than inside your building.
It's engineered to shrug off the weather. The IP55 enclosure and a -20°C to 50°C operating range mean sun, rain and cold aren't obstacles, and built-in module and cabinet fire suppression keeps an outdoor asset safe with less reliance on site infrastructure.
There's less to wire and less to source, too.
A 200A DC disconnect and a 160A internal fuse are built into each cabinet, so much of the balance-of-system that usually surrounds a commercial battery is already handled. Each cabinet is a 307V nominal bank of 5.12 kWh LiFePO4 modules, communicating over CAN 2.0 / RS485.
And the growth path is long. Start with a single 61.44 kWh cabinet, add up to 6 per inverter, and parallel up to 6 inverters for 2.2 MWh of storage and 180kW of AC power — with peak shaving, DER-program participation and grid sell-back all supported as your strategy develops.
