Hello all,
A bit of a puzzle here.
I have a 5kva easy solar installed. It has been working great as an ESS system with a Pylontech us3000 bank.
The grid has been permanently removed by some budding entrepreneurs recently with no hope of being restored we decided to change batteries to Solar MD.
The Inverter has been reprogrammed for the new batteries and ESS removed as we are now off grid permanently. CCGX dutifully rebooted after the Pylontech removal.
The problem began when we decided to add the logger v2 for the MD batteries as we are thinking of paralleling a few for more storage.
Wired up the logger using the manuals and the article https://www.victronenergy.com/live/battery_compatibility:solar_md plugged the logger into the CCGX and the inverter switches off. No problem it restarts but now there is no solar, the ccgx does recognize the bms and reads data off it though. It is sitting at 56% yet no solar for charging, the yield before the plug in is about 2700w. Yet if a larger load switches on in the house the solar kicks in and runs for a bit then goes down to 0w again.
Charging the batteries is a priority and we unplug the BMS- reset the mppt as it has error #67 and reprogram it. Solar charging back to normal.
Have tried several times now plugging and unplugging and repeating the reprogram process on the mppt each time. Rebooting the CCGX after plug in and unplugging.
Initially we thought it was because all we did was change voltages between the two batteries. Had reset the whole system to defaults and started again.
Tried then updating all components and treating it as a fresh install, update all firmware and reprogram. Still no change. If the logger is plugged in there is no solar yield.
I have been in contact with Solar MD and the logger settings have been checked out the wiring and tweaked settings, the bridge is ok, and the logger is ok and reads the data from the GX correctly. Their customer service is great. The logger is viewable on the myPower Portal so connecting to the internet fine. The only thing that seemed out of sorts is seen on the VRM where the battery monitor is seen as Pylontech the device was deleted. But i see when i reconnected the bms again today it shows a Pylontech again
Any other ideas? Or anything we may have missed?
