Exactly ..... why would we be making recommendations about soft starts and another pack when we already know this pack is at a low SOC and simply may be getting a voltage sag which is kicking out the inverter because of that?
ok, ill do that, and ill let u know what happens.
Go to the manual for your fridge and get the startup current, or peak draw, or however they word it.
We are doing differential analysis between the inverter and the bms with tools that the user probably has on hand.
Sorry, but I think we are just shooting blind if we don't know what the fridge is actually pulling.
And the heater draws ~135 amps.
I disagree and I'm the one who suggested the clamp meter.
His inverter has a low voltage shut down at 10 VDC and an alarm at 10.7VDC. An alarm wasn't mentioned so I half suspect the fridge's peak draw pulled the battery down so fast that the battery's BMS shut down before the inverter even sees the drop and has a chance to sound an alarm.
Its might be both.
He said the voltage is dropping to 12.7 .... but I don't think we really know what the instantaneous drop may be.
my lead-acid batteries were doing the same thing.
That would point to the inverter as a problem .... unless those old batteries were weak also.
so not the same thing
ya, they were about 6yrs old. it was 2 6v golf cart batteries from Costco.
