Hi all
I am installing 4-160 W 12v solar panels on my van that will charge either a 12 V 400ah or 24 V 200ah battery (depending on how I configure the batteries)
Leaning towards the MPP 24 V hybrid solar charge controller inverter. It seems to be the best Value and all in one solution for the...

160 WATT 12 VOLT MONOCRYSTALLINE SOLAR PANEL
SKU: RNG-160D-SS
Max Power at STC: 160W
Open Circuit Voltage (Voc): 22.9V
Short Circuit Current (Isc): 8.37A
Opitmum Operating Voltage (Vmp): 20.2V
Optimum Operating Current (Imp): 7.92A
Operating Temperature: -40°C to 90°C...
It’s just too good to be true they clean their batteries can be used down to -20° C

Thanks for your great reply.
I’m going to run two panels in series connected parallel to two other panels in series....I’m going with the MPP 24 V hybrid unit that Will recommends.... waiting for my batteries to arrive but I’m building a 200ah 24v Battery using prismatic cells and a daily BMS
I have a 24 V battery and a Daly bms
When I check the voltage from one end of the battery to the other I get 27.1 V
when I short out the negative cables off the BMS and then plug in the balance leads it starts out at 27.1 V and then the voltage continues to drop until it reaches the 14 v...
Hi All Looking for some advice.
I found these batteries on Alli express 4PCS NEW 3.2V 200ah
The plan would be purchase eight and either make 2-12v 200ah (400ah) total batteries or 1-24v 200ah battery using the either 2-12v or 1-24v Daly bms.
i’m leaning towards going for the 24 V option it...
Ok now that we have identified that the price I was looking at was too high (Thank you Ghostwriter) Im still in need of guidance in regards to the question of 12v vs 24v and the bms
thanks
Perhaps because as an example every time Will tests something with a low temperature disconnect it fails... I’m not saying that this isn’t exactly what it says but history shows when it comes to LifePo4 batteries that claims and reality can be two very different things
