So far no issues since changing settings in the Growatt. Recap: At 26.48 +/- 0.01v the BMS would go into "Short Circuit Protection" fault. Time frame didn't seem to be a factor, neither did load or inverter on or off, just whenever it hit that voltage. Originally thought the Orion 24/12-70 was...

It was randomly timed, but after having the issue come up a few more times, and digging into the metrics from the BMV 712. I've found that it always occurs after the battery reaches 26.48 +/- 0.01v. I had my growatt 1: UTL as it's primary source. I've since switched it to 1: SBU and 14: SNU...

I've done the same with also a precharge resistor and momentary switch. But the original problem of my battery BMS faulting for "Short Circuit Protection" is still happening randomly. I even disconnected all DC loads including the Orion, installed a Victron BMV 712 with beta firmware to log...

I would say that is it. I used a 25w light bulb. With the breaker off to the Orion, the Orion switching plug removed and all-in-on disconneted. After the spark to the light bulb, I turned on the breaker then put the Orion switching plug back in and everything worked.

After turning things off and on and disconnecting and reconnecting I think I found some interesting information. Basically if the all-in-one is not actively charging the battery I cannot connect the Orion. The remote switching plug has no effect on this issue. If the positive cable is connected...

I tested some of that yesterday, if I remove the 12v positive side of the Orion I still get a short circuit disconnect. If I remove both the positive and negative of the 12v side I will also still get a short circuit disconnect. If I remove the 24v positive side and leave the 24v negative...

Post #6 I answer some of the questions, sorry it wasn’t marked as a reply. I’ve cleaned all the connections and made sure they are tight. All cables under even full load are room temperature. PV Input is the label for the hole above it.

I’m using as a step down converter for running a 12v dc fridge that maxes out at about 10-15 amps, diesel heater and a few led lights. Am I using the wrong victron product for stepping down to 12v for the few things I need? I have a older pic before adding the breaker before and after the...

I didn’t phrase that correctly. It causes the bms to trip the short circuit protection.

This needs more testing to confirm. But when the all in one is NOT charging the battery I wasn't able to turn on the Orion without it faulting. But when the all in one is charging the battery the Orion could be turned on. Screenshot of it under load while charging.

I'm not really sure. It's coming from inside the battery, front on the negative terminal side.

I managed to get this to occur while monitoring the BMS. I did hear some rapid ticking from the battery when I turned on the breaker to the Orion. Spent time to double check all the cables are secure and tight with no dirt or grease on the connectors. All cables and connectors stay room...

I haven’t had a chance to plug my computer in to see. I’ll attempt to get some info the next time it happens.

We are using a Orion 24/12-70 to step down to 12v from our Eg4-lifepower 24v battery. The problem is everything works fine for hours or days and then the BMS will stop power. If we disconnect the Orion the system comes back up as normal. If you leave the Orion connected it will continue to...
