Big Battery-48V Off Grid Home Elite Max System - Growatt 6K + 19kWh KONG ELITE MAX Battery｜LIFEPO4 Power Block｜Lithium Battery Pack + Inverters + Cables｜Currently On Backorder

The 48V Off-Grid Home MAX System is designed to provide power for all the electronic devices and heavy-duty home appliances in a 4-6 bedroom home. This system can be used as a backup power source during emergencies or as a fully off-grid wind/solar power system for larger homes. It is a powerful system that utilizes the latest inverter and battery technology, and it is competitively priced in the United States.

The system includes a 48V/15kWh KONG Elite Max Battery with a color LCD Smart Display and new LFP cells that are expected to last for 10-15 years, depending on usage. The battery is calibrated to the included (UL Certified) 15,000-Wh Growatt Inverter, which provides enough AC power to keep all household appliances running smoothly. The kit comes with all necessary components and parts, making it easy for a local low-voltage electrician to install in less than a day.

The 48V Off-Grid Home MAX System is compatible with AC power, wind, solar, generator power, and any other redundancy combinations required. It connects to shore power, allowing the battery to automatically charge when connected. The low-frequency inverter included in the kit eliminates power spikes, which helps extend the life of electronic devices. The kit includes the safest LFP battery technology with built-in triple-safety redundancy features and a UL Certified Inverter. The system requires no maintenance and lasts 300% longer than lead-acid off-grid systems. Additionally, all battery packs come with a 10-year warranty.
