    12vdc solar controller seems to work but not charging ?

    AH! Damn camera angle. 😆 Can you give us some more info on the panel you're using? That 30v should be VOC, but it shouldn't drop that much once connected.... And the model of the solar controller, maybe we find a manual for it? Could possibly be a setting is wrong.

    Might help to move the battery positive cable to the battery positive connection on the solar controller, not the load positive connection. That might fix your problem. ;)

    JBD BMS Toast?

    Check the sense leads to the JBD to verify the app voltage readings. If they are the same as the app, the connections at the battery are suspect. If they are the same as the individual voltages, the BMS may have failed. Let us know what you find. :)

    Wiring question

    Depending on the voltage/amperage of your solar array, your best bet would be to use a DPDT Center off switch, like this one: https://www.walmart.ca/en/ip/DPDT-6-Pin-3-Position-On-Off-On-Metal-Toggle-Switch-240V-15A-120V-20A-AC/PRD1C1CH5RDVQCH The battery switch you propose to use, are only...

    Designing and sizing a limited mobile system

    Kind of.... If all 6 100w panels are paralleled to the charge controller, yes, any of the 6 could be shaded, and the others will still produce. Same with the 300w panels, in parallel, one could be shaded, the other will still produce. That said, if you serial all 6 100w panels, or both 300w...

    Designing my first solar system for my van. Please critique my diagram.

    Would like to point out that since you upgraded to the 3000W Giandel, carry the 2/0 wire all the way to it. You also need a fuse at the positive busbar to the 24v fuse block. Your negative cables on the appliance side should also be 6 AWG. A 20a CB on the panels main positive would be a handy...

    Batteries will not charge-Abnormal Cells Voltage Error

    @Rapidrob is it possible you have the Air8 set to the wrong chemistry, thus getting the error? Li-ion vs LiFePo?

    Is it safe to have a 30a to 50a adapter connected with the Victron multi plus II?

    @MrM1 you do not get split phase 240v from any 30a to 50a adapter. It just connects L1 and L2 on the 50a side.

    50A Shore power neutral to Growatt 6000T?

    Hmmm, are you able to tie the neutrals in the main panel, not at the Growatts neutral? that might be the difference, but I can't see why it would. Gonna show my electrician friend the 2 pics and see if he has any suggestions.

    50A Shore power neutral to Growatt 6000T?

    You have it plugged into shore power, and it's all green now? But get an issue if you connect it to the growatt without the neutral? Just making sure I'm understanding right.

    50A Shore power neutral to Growatt 6000T?

    I re-read your initial post, and then your last post. The surge protector is telling you no neutral from your shore power. Double check that your shore power is wired correctly. Is the Surge protector this one: https://hughesautoformers.com/product/pwd50/ Or this one...
