It gives redundancy yes, but your 'poor weather conditions' performance will be reduced in comparison (even in good conditions, your...

What about 3 victron 75/15... one on each panel. A bit odd, but saves money and has redundancy. They can be had for 67$ each. 🤷‍♂️

Mine are 60A 150vdc mppt charge controllers but even a 40A 150v would be ok (250v has got more headroom and would allow adding a fourth...

ok, makes sense. So I should upgrade to a Victron 250/60 solar charge controller to be on the safe side. Does that sound right? Thank you!

ok, great. So instead of the EPEver mppt at 40 amps, I should get something like the Victron 250v/60a mppt solar charger which has a max...

Nope! You will have a dead mppt. For the max voltage you look at the Voc (Voltage open circuit), With a Voc of 46.6 * 3 panels = 139.8v...

Often on RV’s because we park under various shade, it is usually better to wire panels in parallel than series. If I found the same...

I was going to get the 40 amp, 4215 and it sounds like parallel will be better for the solar panels.

yes, the max pv open circuit is 138 volts at 25 degrees C for the EPEver Mppt at 24 volts. I was using VMP instead of VOC. I'm still...

On cloudy days you will often only get 7 to 10% of rated power - thus you will be lucky to get 60watts from a 600w array. Series might...

ok, thank you!

The EPEver MPPT at 24 volts has a voltage range of 26v-108v and a max pv open circuit of 138volts. If I'm reading things right, that...

I meant to say I was going to put them in series. I was told putting them in series will give enough voltage on cloudy days to charge...

The 4000 watt 24 volt inverter was less expensive than the 3000 watt Giandel inverter. The 3000 watt would be fine. I sharpen out of my...

I could use a 3000 watt inverter, or even a 2000 watt. I am using tools for sharpening and lights. One machine might use 3.5 amps at...

Hello, Would this system work for my van (hightop econoline)? 2-SOK 24 volt, 100 AH batteries rec charge- 20 amp max charge...
