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:
Selectable charging current;
Overload and short circuit protection;
Auto restart while AC is recovering;
Perfect pure sine wave output;
Built-in pure copper transformer;
Support sealed battery and lithium battery.
