AC Outlet Filter
The AC outlet filter connected between inverter and water pump. It should be used for Jntech H series solar pumping system or high head/long cable solar pumping system.

System optimization for long cable reflect in the following 3 points:
(1) Effective control of motor reflected voltage, protect motor insulation, prolong the lifespan of pump;
(2) Effective suppress the surge voltage on the electric cable, protect inverter power module;
(3) Filter out PWM control high frequency harmonic, pump running more stable, improve system efficiency.
Input and output terminal of outlet filter installed in the bottom, all of them are M25 water-proof, as is showing Fig.2 Output cable switch in outlet filter through the terminal of “INVERTER”, and output cable of outlet filter switch in terminal of pump motor through “MOTOR”.
