Jntech Low Frequency 1000VA 24 Volt Solar Off Grid Inverter MPPT Charger Controller
1. Introduction
JNTECH off-grid system is mainly composed of solar panels, solar off-grid Inverter and Battery pack. Solar off-grid inverter is the core device of the system, it converts DC power produced by solar panels to AC power to provide electric energy for loads. Solar MPPT charge controller stores the surplus solar energy into batteries; when solar energy is insufficient, or at night, the battery pack will be discharge to replenish energy for loads.
2. System features:
Special AC output design, adopt emergency & heavy loads separate control;
Advanced BMS;
Silicon-controlled rectifier be adopted in AC by-pass;
Compatible to mains voltage or generator power;
Provide power supply to loads for 24 hours per day;
Support sealed battery and lithium battery.
