Devanté

I think you might have hit it on the nail. I unfortunately do not have a BMS on my 12v lithium batteries so I use User settings however I did notice on the battery balancer, A huge spike in current when I set my max charge current to 40a even 30a. So I think it might be overloading or like you said exceeding the max that's when the error kicks in and the inverter restarts. 20amps is actually ideal since I get that from my panels during the day so I almost don't even use the grid. Edit- the batteries do have BMS but not as smart as yours, only there to protect the battery from overcharge, etc. Does not handle Amp/V hence the battety balancer

Hi Wayne, Glad to hear it's working, yeah that error gave me nightmares. I am not sure why we get the error when the max charge current is set to higher than 20a, I assume the batteries don't like it or something to do with th inverter but ay, at least there is a fix

Good luck man Just remember on AC we only get 20a max from our grid. Also check the highest amperage your battery can take.

Hi Wayne, I had the same issue. Ensure your Max Ac Charge current is set to 20amps not higher. I actually have mine set to 20amps Max Charge Current - saves on electricity and I don't mind the trickle charge. I am running 4x 1.5kw 12v hubble batteries with a battery balancer. Below are my User settings I found to work best for me. Float is set to - 54.8v Bulk is set to - 56.4v Cut off set to - 46v I noticed when I upped the Max Charge Voltage to 30a or even 40a then I would get that error even though my solar panels are capable but it seems the batteries don't like it, even if Hubble says it can do 40a for 4x 12v batteries in a bank. I use 20a max. Do you exhaust all of your 5kw during stage 6? I get through stage 6 easily which is 4 hours for us. Hope that helps

Sounds complicated, I will then use the inverter as is thanks Coulomb

Hi Coulomb, I trust you are doing well? Where can I get the latest display firmware, 130.06? Is there a changelog available?

Thanks Coulomb, What would your recommendation be? To leave the firmware as is?

Hi Coulomb I bought a mecer 5.6kw SOL-I-AX-5M4 inverter. Current CPU firmware on the unit is 52.00. Is there any update for this model?

Hi Coulomb, Thanks for the prompt response. I guess I'll have to take it up with the retailer, maybe get this one swapped for a 5kva model if they cannot help me. Thanks once again.

Hi Guys, I am struggling with the premature float bug, Inverter model is the RCT alm 3k 24v, Any firmware update that solves that issue? Currently on V 7.11
