You have set the battery capacity to 90Ah and not 9.0Ah? :?

Hmmm.... definitely had 90AH as the battery capacity, but may just have had 9.0Ah as it’s startpoint 🤔

Just reset to 80AH as current SoC and will see how it goes overnight... here’s hoping I made that silly a mistake! :oops:

Bought the NASA bm1, mainly because lovely big display that can read without needing specs on. Bit more expensive.

Embarrassingly, I think this was it as we woke today with 43.5AH remaining for the first time... Thanks again Scubadoo!

#6 turned up in just 12 days. I think that's an Aliexpress record for me! Functionality TBA, install to happen weekend.

Installed tonight.

Short story - installed, wireless signal connected straight away, looks good.

Long story - nightmare. Disconnected link to battery during install, but mains charger still had DC powered from the other side of the connection. Bolts on shunt aren't captive, one fell down inside the shunt and shorted it, frying a couple of tracks on the PCB. Thankfully I was able to repair it with a couple of jumper wires and we're away again. Entirely my fault. ISOLATE prior to install! .

Fitted the 300 amp Juntec to my Southern Star. Easy, perfect thanks for the recommendation. Still getting to grips with the "bat" settings but guess will come right. Have my 1500 watt inverter running through and interesting readings. Nearly 100 amps using the Nespresso!
