I am about to install some 425W panels, and just thought of testing them ahead of time. Is there a standard procedure to use? Just check the Voc with a multimeter, then connect their leads together and check current with a clamp meter?
Sounds good. These are new, so hopefully that'll take a little variance out. These are 80"x40" and cost $160/ea. So a little over $.05/inch. I'm going to swing by there tomorrow to check things out. I'm not sure how to test the things you mention, but there's YouTube! Hahaha.
Yeah that works. You can do both tests with a multimeter.
How do you measure short circuit current with a regular multimeter? Mine has a 10A maximum.
Guess it's panel specific. All of my panels are under 10A so the multimeter works OK.
Can you use a clamp meter for a short circuit amp test?
Yes you can use a correct clamp meter (DC). I have tested every panel I own "BEFORE" installation.
Yep
Yes, I have done this to all my San Tan panels as well, works pretty well.
Thats kind of a loaded question, but it all depends on what your plan on running and your budget!
Is this a secret?
I’ll be running 1620w of solar at 24v. I’d like to have a 3000w inverter. Is that the details needed? Budget isn’t a huge concern, but within reason. I don’t want a $1300 system when a $500 will work perfectly fine. I’m not necessarily looking for the cheapest thing possible neither.
Sorry, I thought that was coveredin an earlier post. I’ve ordered 8 Lishen cells from Michael Caro’s group buy. Once those come in, I’ll have 272ah in 24v configuration.
I’ve looked at that one, I was just hoping to have it sooner than the end of June. How about that MPP? It’s only a 2400w inverter, but that may work, or should one hold out for a 3k unit? Obviously it depends on my consumption, but is there a big difference?
