A 6000W, 48V split-phase inverter charger for 120V and 240V loads
The LFP6K48V240VSPL is SunGoldPower's 6000W, 48V low-frequency split-phase pure sine wave inverter charger. It takes 240VAC input and supplies 120V and 240V output, combining an inverter, a 60A battery charger and an automatic transfer switch, with a surge rating of 18,000W for 20 seconds.
It is built for small homes, businesses, RVs and off-grid or backup systems with a 48V battery bank. AC or battery priority, automatic generator start and an adjustable charge current are included, and SunGoldPower lists this 48V model to the UL 1741 standard. It has no built-in solar controller and is not designed for parallel use.
120V and 240V split-phase output
Takes 240VAC input and supplies two 120V legs or 240V at 50 or 60Hz, for homes and businesses with a 240V panel.
- 6,000W continuous, 18,000W surge for 20 seconds
- Low-frequency transformer design; starts motors up to 6HP
Built-in 60A battery charger
A 3-step smart charger for a 48V battery bank, with charge current adjustable from 0 to 100%, or switched off.
- 9 battery type settings, including LiFePO4
