No. I have the original 180w panel and I installed another 180w panel and wired the two in parallel and then I have an external 220w panel.Bill&Suze said:@elbolillo, do you have the Black Canyon 400 with 620W solar to feed those 400ah?
Yes, that is a good process to establish 100% SOC and it makes no difference which side of the shunt you connect ground. But, if you want the shunt to keep track of the portable charger contribution to the battery's state of charge in the future, the charger ground should be on the "load" side of the shunt. This will also allow you to monitor the portable charger performance.Sharon_is_SAM said:Ok. So, if I charge the battery fully with the portable charger on the battery, then sync the Victron BMV, will the BMV SOC be accurate on discharge?
