I have a setup running a Phoenix 12/800. It is all running very nicely with one issue:
We have a very small (43L) Ikea fridge/freezer which uses only about 30W continuous power when on. The problem is, when it cycles to ON (ie compressor kicks in), it demands such a peak that the inverter jumps into the red zone of the meter (bluetooth app) for about half a second before coming way back down to 30W. In this time the inverter is clearly struggling and the lights dim etc! While plugged in, the fridge cycles on/off once every 5-10 minutes. Naturally we have now disconnected the fridge.
- Is there some utility to 'absorb' / 'smooth' this peak as not to stress the inverter so much? Will a surge protector do this, or just turn off?
- Are there fridges with smoother / softer peaks, or is this a universal issue?
FYI: Battery bank is 3x 280Ah 12V, with 35mm2 wire connecting. Wire from battery bank to inverter is 25mm2, which i believe is the largest you can fit into the connectors on the inverter housing.
Update: some have recommended soft start modules, if anyone can recommend a specific unit I would be grateful!
Many thanks for any input!
