I was thinking about using a simple wall wort (its a 20v, 2 amp) and plugging it into my 12v PWM controller for my small setup to charge when solar is unavailable. I have one of those small power meters right before the PWM Solar input, but noticed when i connect the wall wort's positive and...

Has anyone had any experience with this small inexpensive MPPT Charge controller? https://www.amazon.com/dp/B09S3PHNTQ/?coliid=I118U8QSO8AHWW&colid=5LGMID9NZOMV&psc=1&ref_=lv_ov_lig_dp_it It was the first one i've seen in this form factor and while its only 10a, it might be an interesting...

I was looking at some cheaper aliexpress "pure sine inverters" and saw feedback on one that showed a trapezoidal waveform and the buyer complained it wasn't pure sine. As far as I knew there were pure sine and modified sine waves, but trapezoidal was new to me. Anyone else have feedback on if...

I currently am running 4x 100w panels in series which roughly runs at about 80ish volts into this mppt charge controller https://powmr.com/solar-charge-controllers/mppt/powmr-60amps-12v-24v-36v-48v-mppt-solar-charge-controller/ The odd thing I have noticed though is, when i check in on my...

I have a small 100w solar setup with a two 12v battery in parallel with about 560 wh capacity I was wondering, if I could somehow use an extension cord 16AWG to connect my panel to my charge controller to save me from having to plug my battery in next to the solar panel? I checked and 16AWG...

I have a small 300w variable lab bench power supply, but was wondering if I could use it off a modified sine wave inverter? I'm just not sure a modified sine wave is stable enough. Anyone know if modified sine wave power would hurt my lab bench power supply?

I have a small 12v LiFePO4 solar setup 100w Panel 16ah Miady 12.8v LiFePO4 Battery 12v 410W Inverter Schumacher brand 12v 30amp PWM Solar Charge Controller I know my system has no low-temp cutoff, but I wired up a cheap 12v temp controller...

Hey everyone. I have a DIY "solar generator" that I built (roughly 300-500wh of 12v lifepo4) and a PWM charge controller. If I wanted to charge it with my car through the 12v power socket, how does that work? What limits the amount of current demand my batteries will draw from the car? What...
