Description
The Growatt hybrid solar inverter WIT 8–15kW series is a smart, three-phase unit that manages power from your solar panels and the 48V battery. It has built-in MPPTs to pull the most energy from the sun, mounts on the wall, and is IP66 weather-ready for indoor or outdoor use. It works with common LiFePO4 or lead-acid batteries and should be connected to batteries for normal operation.
Think of it like a simple power manager for you. On sunny days, it uses solar first to run your appliances and charge the batteries. When the sun fades, it automatically switches to the grid so your electrical equipment stay on. You can choose what to use first—solar, grid, or battery—and change it anytime. If you need more power later, it can work together with other matching units to grow with you.
