The iCON 100kW 215kWh Battery Storage System is a fully integrated, on or off grid battery solution that has liquid cooled battery storage (215kWh), inverter (100kW), temperature control and fire safety system all housed within a single outdoor rated IP55 cabinet.
Total Cost Reality: While battery units cost $7,000-$12,000, total installed systems range from $8,500-$17,000 due to installation complexity, electrical upgrades, and supporting equipment. SolarTech upgrades your system with additional panels or battery storage.
