Description
Commanding whole-home backup with room to grow, this bundle pairs the Sol-Ark Limitless 15K hybrid inverter with two UZ Energy IG-16K-U outdoor LiFePO4 batteries. You get 15kW of output, 200A grid passthrough, and 32kWh of storage.
Key Features
- 15kW Hybrid Inverter: Delivers up to 15kW of continuous power, 12kW from batteries alone, and 24,000 VA of off-grid surge for 10 seconds.
- 32kWh of Outdoor Storage: Two 16kWh LiFePO4 batteries rated IP65, with tier-one LFP cells and more than 8,000 cycles.
- High Solar Capacity: 3 MPPTs with 2 strings each accept up to 19.5kW of PV, with AC coupling available through the generator port.
- Seamless Backup: 200A grid passthrough and a 5 ms transfer time keep loads running through outages, with automatic generator start support.
- Built-In Battery Safety: Each battery includes a fire extinguisher, heating film, decompression valve, and an advanced BMS with automatic parallel configuration.
The inverter’s integrated protection includes arc fault detection, rapid shutdown, ground fault detection, and a PV disconnect. It is IP65 and NEMA 3R rated, and it runs at under 30 dB.
The batteries charge down to 14 °F, and mount on the floor or wall. They support CAN, RS485, and Wi-Fi communication, and up to 64 units can be paralleled.
Both components carry a 10-year warranty. Up to 12 inverters can be paralleled for larger systems, with Wi-Fi and LAN included for monitoring.
