Product FAQ's

Can I use this battery system completely off-grid?

Yes — the King Kong 2 is built specifically for off-grid and hybrid energy systems. It’s ideal for powering cabins, homes, workshops, and industrial setups that operate independently from the grid. With 62kWh of usable energy and high-discharge capability, it can support full-time off-grid living, solar integration, or backup power for extended outages.

What type of inverter should I use with this battery?

Yes — King Kong 2 is designed to work with external 48V inverters. It outputs a nominal 51.2V and supports up to 500A continuous discharge, which equals over 25kW of sustained power. Just make sure your inverter is compatible with battery specs.
For large-scale applications, pairing with high-power inverters is commonly recommended.

How long can this battery power my home or devices?

With 62kWh of usable energy, King Kong 2 can power an average off-grid home for 1 to 3 days, depending on total energy usage.
For example:
At 2kW continuous load → up to 30 hours
At 5kW usage (typical peak + appliances) → around 12 hours
Actual runtime depends on your load profile, usage pattern, and whether solar or generator inputs are supplementing the system.
