Description
Equipping your home with whole-home backup and solar self-consumption, this bundle pairs the Sol-Ark Limitless 12K hybrid inverter with two UZ Energy IG-16K-U outdoor LiFePO4 batteries. Together they provide 32kWh of storage and 10kW of continuous backup power.
Key Features
- 12kW Hybrid Inverter: The Limitless 12K delivers 12kW to the grid or 10kW of continuous backup from batteries, with 24kW surge power for 10 seconds.
- 32kWh of Outdoor Storage: Two 16kWh LiFePO4 batteries rated IP65, with tier-one LFP cells and over 8,000 cycles.
- Flexible Solar Input: 3 MPPTs with 2 strings each accept up to 19.2kW of PV, with both DC and AC coupling for new builds or retrofits.
- Seamless Backup: 100A grid passthrough and a 5 ms transfer time keep loads running through outages, with smart load control and generator 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 handles loads such as mini-split A/C systems, well pumps, kitchen appliances, and furnace blowers. A built-in PV disconnect, arc fault detection, and rapid shutdown meet the key NEC requirements.
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, and the inverter is a U.S. company, non-FEOC product. Monitoring runs through the MySolArk mobile and web apps with VPP enrollment support.
