Hi We have a system with 8 Pylontech US2000 C bats Linked to a Sunsynk 8Kw inverter - the system is running fine but have noticed that one battery is not running charging as per the connected Pi with ICC In the mornings it looks like this. Battery no 4 is also not charging fully to 100% during the day - only about 40%. Is this battery kaput and should it be removed? all dip switches are fine and connections also X2 checked. any advise would be appreciated

Brilliant - thanks - working fine. Was worried about the license file

Running new version 3.4 gives me this error - I have copied the registration file over

Just to confirm they did adjust that setting to 50hz grid default

Interesting info - thanks . I eventually told the guy with the problem to submit a ticket to Goodwe which he did. They responded the same day that they had made adjustments to the device and he should monitor if the issue is resolved - which raises the question as to how much can they do remotely - possibly it was just the 50hz setting - will check when I am at his place again what PV Master says. Needless to say very impressed with the quick response from Goodwe

Can anyone explain this to me - DC Injection High? What does it mean - the manual just mentions it but no explanation as to what can caiuse it. When this happens the pv generation drops resulting in ver low daily PV generation - the 'error' occurs multiple times a day causing the PV graph to show a general up and down output instead of a constant smooth output line
