Hi All,

After some help from the list and DIY solar power forum I’ve created the
attached diagram. Thought I’d post it in case it could be useful to anyone.
Hope everyone has a great Christmas.

yes but.  the panels never generate the rated watts in the real world. best to 
monitor output in your specific locale / application.  No need to make an 
expensive upgrade for something that will never happen.  I run 2x 100/30 amp 
controllers on 2 sets of 4 x 150 watt panels in the baja.  They never make more 
than 10 amps.

Actually, the controller should be even bigger (400 W/12 V = 33.333 A). A 30 A 
controller will be marginal, at best. If you run it like that, it may generate 
excessive heat and may fail prematurely.



The voltage would depend on how the panels are connected. If all in parallel, 
then the voltage should not exceed 20-22 V.

controller is likely needed for 4 panels.  they could generate over 80 volts.  
Your Victron has a switch for different battery types if you change system in 
the future.  Also be sure to fuse or use a breaker in the system between panels

Hi All,

Starting to look at the project list for the spring and I have a question for 
the group.

I have 4 100 watt solar panels that are connected directly to a solar generator 
(Bluetti AC200P) that is wired to the AC panel. When I want to charge the house 
bank I flip the switch for the House bank/start bank charger. Obviously not the 
most efficient way to charge but works. I have a Victron solar charge 
controller that came with the panels that I would like to use. The question is, 
can I run the solar panels into a two way switch. One side going to the charge 
controller and the other going to the solar generator? That way I could charge 
the house bank till full then switch it over to the lithium.

Thanks everyone.
