Re: Inverter for 48v off grid - PIP xxxxx or something else?

You could just connect panels direct to the hws heating element. Say 8 x 300w 36v panels in series.

Re: Inverter for 48v off grid - PIP xxxxx or something else?

I have connected the 2 existing 4800w elements in series. This gives a total of 2400w load. The reason I did this is because 4800w for 1 appliance is a bit much for 2 x 4048V inverters. There would only be 3200w left out of the 8000w total available. Yes on the ac side. The modification to the HWS i...

Re: Inverter for 48v off grid - PIP xxxxx or something else?

My existing hws 415L has 2 4800w elements. Previously the top element had off peak rate grid power connected via the top thermostat continuously and the bottom element had off peak rate timed grid power connected via the bottom thermostat. I connected both elements in series to give a total load of ...

Re: PIP inverter repairs and hardware modifications

New type scc boards can be fitted to old type 4048ms with the big black heatsink. Leave the heatsink but remove the old scc pcb. Mount the new type scc pcb between the 2 main board heatsinks sand connect to the 2 inductors which remain on the big black heatsink

Re: PIP-4048MS and PIP-5048MS inverters

I don’t think there is any exact battery voltage settings for agm’s with pips. Depends on number of panels, number and size of batteries, temperature and usage. I tend to always set bulk at 58.4, float 54 - 56, LVD 46. That’s using non Australian firmware without kettle komp. If you have utility ava...

Re: PIP-4048MS and PIP-5048MS inverters

Good now with fans upside down. Even the big black heat sink is getting hot from the hot air being blown upwards. There is no scc pcb attached to it.

Re: PIP-4048MS and PIP-5048MS inverters

I just turned the fans around. Fans are running slow with 350w load and no solar. Even with 1.5kw load, fans were slow. With more than 2kw solar, the fans were fast and temperature was 50. Will see how it goes with fans turned. Would be better if fan speed was controlled by inverter temperature. Tem...

PIP-4048MS inverter

Tried connecting a generator to 2 4048 in single phase parallel. 28 PAR. Would not connect in either APL or UPS. Changed 28 to 51G and the one inverter connected to the generator connected on APL. Could only charge at 10A because it was a small generator. I have connected a 3 phase generator to 3 40...
