Measuring open circuit voltage on Renogy 100W suitcase
Hi folks - the support line is impossible to get through so I am hoping someone can help me out.
I am completely new to solar and RV-ing. I was planning on using a 100W Renogi suitcase (with 20A controller) in an RV I am renting. This is the unit I bought - https://www.amazon.com/gp/product/B079JVBVL3/ref=ox_sc_act_title_4?smid=ATVPDKIKX0DER&th=1
When the panel arrived, I wanted to test it - but didn't have a battery yet (was planning on using the rental RV's batteries).
So I tried out the open circuit voltage and short circuit current tests - and got ~0 for both. I basically followed these instructions - https://www.renogy.com/blog/how-to-troubleshoot-your-solar-panels/. Took the panel out to face the sunlight directly and used a multimeter probe to check at the output leads that would go into the batteries.
Am I doing the test wrong or did I get a lemon?
