I bought a few extra solar pannels and stupidly fitted them with little knowlage
I have a H1-3.0-E-G2 4500w inverter and 10kw battery system all was well for 24 hours after the upgrade on the sunniest day of the year
But the next day I havnt been able to get anything from my batteries the accept a charge but no output
Having looked at the max amp's I see was over by about 4amp and assume I have fried something
Any help would be greatly appriciated
I can get a used BMS the same as mine for a good price if needed

The BMS is there to make sure that you can’t provide excess power to the batteries, if there was a problem it will throw an error and disconnect the main contactor - it won’t re-connect itself unless you power off and restart the batteries.
But something doesn’t sound right as you are saying they will accept a charge which implies they are connected, the contactor is closed and none of the fuses have blown.
Can you provide a bit more detail on which batteries you have HV2600, Mira, ECS etc.. - are there any error lights or messages?, have you restarted the battery pack and/or the inverter.

The batteries are HV2600 's mk1 There are no errors I can see
I have rebooted the batteries a few times and the inverter
I have just set the system to charge from the grid for a few minutes and 3500 w goes in but when I stop the charge I only get 55w back out
Everything else looks ok just very short on discharging the batteris

I was going to say check you dont have a charge period set with the charge from grid turned off - the charge time must be 00:00-00:00 when not in use or they stop the battery discharging - also check your minsoc’s are both set to 10%
Thanks for your input
I dont know what has realy been going on but everything is fine now
I have re wired my new panells in series and the amp rating is well below the max and the voltage is easily inside the limit
I am sure the ampage was way over the max yesterday but I never actualy looked at the inverter info while it was working yesterday "I didnt know how"
I keep learning things
