I have a small system with 3 arrays of 3 340W panels each. Each array is handled by an epever mppt controller. I was check on my SOC and I noticed I was lower than I expected. A quick check of the displays showed that array 3 was not supplying any charge. I have an inline fuse on each...

I am sorry to say that this appears to have been an operator error on my part. I was opening the app but I was not selecting the device from the list because I thought it was the "demo device" or somesuch. The blue light does not come on until you open the app AND select the device. My battery...

Well it worked for a time and I never leave the GPS on, big battery hog. I'm using an iPhone FWIW :)

I don't understand why GPS is needed? I tried enabling location services but it didn't change anything.

I recently assembled a 8s 280AH bank using batteries from Docan (thanks Jenny!). It came up easily and after manually top balancing the cells I ran a 250AH discharge cycle, all went swimmingly. After recharging the bank, I started having problems with the bluetooth connection. The blue light...

This might seem like dumb question but here goes. I'm interested in having an A/C powered charging system for my lifepo4 bank. Getting these in substantial amperage is expensive. Now - my battery bank is charged from 3 separate Epever trace charge controllers utilizing 3 separate panel...

I totally agree that watt per watt microwaves are way more efficient than resistance heating. The problem is many if not most microwave ovens have a huge current demand when they start, much like a motor. If your inverter can't handle it, it can't handle it.

While I have not tried it on a microwave, my Samlex PST-2000-24 runs my window A/C unit and freezer just fine. I'm happy with my Samlex.

Solar generated battery-saved electricity is not really a viable option very often. Unless you can spend tens of thousands of dollars on batteries and panels, think of a different heat source. A typical space heater for home use draws 1500 watts and would not heat even one room in a cold...

It just all depends on where you live. I live outside of city limits in TX. The county is my jurisdiction for such matters. The county cares about sewer/septic and doesn't about anything else. I can do electrical wiring, plumbing, whatever - no one cares unless is has to do with sewer/septic.

Re: chargebacks. CC companies vary some but most I think will fix it if you really got screwed. I live in a rural area a long way from the county road. When UPS delivers, most of the time they bring the package to my house. I ordered 3 charge controllers and wasn't expecting them for a while...

Thanks everyone for your thoughts. They pretty much aligned with what I already thought. but I was leaning toward the series 12V before, now I'm leaning towards the 24V :)

I am a newb although I do presently have a system working (2KW with AGM batteries). I want to add some prebuilt LifePO4 to my 24V system. I am having a hard time deciding between two 12v 200AH batteries or two 24V 100 AH. The 12V batteries would provide more "flexibility" in that it could...
