Build in maximum power point tracking (MPPT) up to 99.9% with fast response speed and stable operation. Suitable for driving single-phase AC Pump, Fridge and freezer
Input voltage: 150 – 450vdc
output voltage: 0 – 220/240vac
rated: 4kw, 16A. Dry run (under load) protection, lowest speed auto-tuning, pumps maximum current protection, minimum power input protection.
Dual-mode AC and DC power supply input is also available
for the digital signal of the water level sensor and the analogue signal of the water level sensor for tank water level detection.
Current limiting: automatic current limitation during operation to prevent frequent over-current fault tripping function for solar pump: intelligent control mode, MPPT, light wake and sleep, auto or wake up, water shortage alarm. Dial switch: run/stop protection: over current
