That is exactly it, my panel 18.6Vmp*3.5A = 65.1W, at the time of testing i had 22.3Voc and 4.5Isc

IIRC i got the full 65W charge rate up to 97% SOC and for sure was getting it below 95% SOC What is your solar voltage under load? I bet its saging quite a bit. If you can get your Voc, Isc, Voltage under load, and current under load As Bob142 said it could be a bad adapter cable, try...

you want the inverter as close to the battery as possible, voltage drop on the 12v side is 10x as bad as on the 120v side

What is your Locked Rotor Amperage? Running watts vs Starting (LRA) watts It is usually 2-3x your running watts so your fridge may pull up to 2484w for 2-3 seconds before the compressor starts turning

Yes just a residence, the 23A is locked rotor as if the pump was siezed, starting surge will be less than that. Full load nameplate is 5A@230v so a 3x surge is less than 4kw Im mostly just looking whats out there thats more cost effective or has more features than mpp solar

Can the magnasine be set to charge a 14s lithium-ion pack?

14s 3.7v liion pack, most likely going to be used EV cells, leaning Leaf at the moment

I just noticed this today, however i was only getting 65w out of a rich solar 100w panel, both brand new and 75% soc, about noon on a clear day i wonder if thats the PWM controller thats hamstringing it or being flat mounted

While their is enough sun to effectively overpanel the needs of both units i would expect them to charge at max rate in paralell just fine, once the sun starts to drop is where it would get interesting as i would expect a pair of MPPT controllers to start fighting to maintain their own power...

Search, Option 1, Option 2, Option 3 My continous draw will be 25-28A so im guessing ill need a 30A+ BMS and i need it to be one of the smart ones since im not sure how close to 16v the small PSW inverters will so i want to set the overcharge cutoff at 3.95v or where needed Thanks guys -squoril

uncle wants to put in solar to run his well pump and im trying to give him a DIY estimate He has a 230v 1/2hp pump which is on a 15A breaker and has a locked rotor draw of 23A, based on 15*230 im thinking a 4kva rated inverter will run the pump and im curious whats out there price wise right...
