Hello everyone,
I have a PIP 2424LV-MSD in an RV. Shore power goes to both the inverter/charger and a GoPower TS-50 (auto transfer switch), and the inverter AC out also goes to the other input for the ts-50. For the last couple of months, everything has been working fine until yesterday. With shore power on and the inverter off, we turned on an air conditioning unit, shortly after (during startup surge) the ts-50 started chattering, and then the breaker at the power pedestal tripped.
I've measured everything I could think of with a multimeter and got some unexpected voltages I can't explain.
With the inverter off or on, shore power on:
- PIP2424 is getting 120 Vac on the input ports
- PIP2424 is putting 145-146 Vac on the output ports
- PIP2424 is putting 26 Vdc onto the batteries
With the inverter off and shore power off, with very small solar input 7-10 watts:
- PIP2424 AC output ports show 0Vac
- PIP2424 AC input shows 0Vac
With the inverter on and shore power off, no solar at all
- PIP2424 AC output ports show (normal) 120Vac
- PIP2424 AC input shows 0Vac
Based on this it does not seem like the transfer switch is wired incorrectly or giving any kind of crossover, I disconnected the inverter output from the switch until I can figure this out anyway. What confuses me is why the PIP2424 would give any kind of voltage on the inverter output even when switched off?
Today I am planning on opening up the box to check the PCB for any damage, maybe from road vibrations?
Any ideas or help would be appreciated, the previous owners installed this inverter about 1-1.5 years ago so it's not too old.
