Sol-Ark L3 HV-40KWH | 40kWh Commercial Indoor Energy Storage System | 208V
⚡ Before You Buy
This is a commercial-grade battery system designed for three-phase 208V applications — not typical residential installations. It requires a licensed solar/electrical installer, electrical permit, utility interconnection, and a compatible 208V three-phase inverter.
The Sol-Ark L3 HV-40KWH is a 40kWh indoor commercial energy storage system designed for three-phase 208V applications — multifamily properties, light commercial buildings, retail, and small industrial facilities. It pairs with the Sol-Ark 30K-3P-208V commercial inverter to deliver a complete commercial-grade solar + storage system.
At 40kWh capacity, this system can cover substantial commercial loads through grid outages or provide meaningful peak demand shaving for facilities on demand-rate utility tariffs. Indoor-rated enclosure, designed for mechanical rooms or utility closets. This is not a residential product — three-phase 208V service is required.
