This document is a user manual for the Maxpower Sunbridge 1000/Sunbridge 2000 MPPT Solar Inverter.
Function Description:
The Maxpower Sunbridge 1000/2000 MPPT Solar Inverter is designed to power home appliances and 3C electronics. It can also handle motor-type loads with high surge power, such as vacuums, small freezers, or drills. With a built-in MPPT solar charger, it converts solar power to battery power and provides continuous power to connected equipment during nighttime. The inverter operates in line mode or inverter mode depending on the utility power status. It can charge connected external batteries even when the unit is off, provided the AC input cord is plugged into a wall outlet. The unit supports various battery configurations, including single, multiple in series, and multiple in parallel connections. It also allows for connection to solar panels, with specific guidelines for PV module selection to maximize charging efficiency.
