I’ve had my 810 AH system setup for a couple years and been running flawless. I’ve had it stored inside in a climate controlled hangar and was getting my trailer ready for use.
Came out to dead battery and noticed my shore plug was showing reverse polarity. Turned out my surge protector failed and was the culprit.
Since then I’ve plugged it in and got some charge back but when on shore power it runs and charges fine but every 70-120 seconds it shuts down completely and restarts like its loosing power. I’m guessing some kind of fail-safe mode?
I’ve checked my hangar power, I’ve tried my generator, rebooted everything and even put a stand alone charger on my batteries.
Everything works when it’s on and my monitor shows no alarms or codes that I could see but honestly I’m barely competent with this system.
I’ve re checked the surge protector and it’s definitely the cause of the reverse polarity fault but not sure it has anything to do with this or not.
Any ideas? Did a power surge fry my protector and screw up my Multiplus?
Did you get an answer? Same here
Yes, I had Battle born check everything and after my tech looked over everything he determined something unrecoverable inside the unit. We are going to send it in for repair under warranty.
I needed my coach right away so I decided to buy another and get the old one fixed and keep as a spare. The new one worked perfect right out of the box. Will be curious to see what they determine once they tear into it.
Damn, that’s not very reassuring!
I’m trying to post this but the site is fighting me!
I hope they fixed it under warranty!
I bought a van secondhand and it his a multiplus 3,000 w inverter.
I installed a new 1500 watt electric water heater. Every time it will run the heater great for exactly 2 minutes and then it will shut it off and do it all over again.
I have run the heater independently on AC power and it works great and draws about $1,400 watts and I have checked the wattage draw at the outlet in the van and it shows the same. The system monitor also agrees with the wattage. So this is less than half the continuous wattage my system is rated for but for some reason like clockwork it will shut off after 2 minutes.
I tried some other high wattage items that draw about the same amount of power in the exact same things happened. It shut off after 2 minutes. I monitored the batteries and they maintain the constant 12.6 volts. I have four battleborn lithiums. All connections are excellent and wires are of appropriate size.
Is there some sort of strange failsafe setting within the inverter I need to modify? The over draw light never comes on or anything.
