Inverter Issues on Existing System
I sit on the board of our HOA and we have a solar panel system at the front of the subdivision that runs a small LED light and sprinkler controller. The complete system was installed about 6 years ago. The original installer is no longer available and we don't have anyone really versed in the system to understand what our problems are. The panel was replaced last year and we replaced the battery 2 years ago. Personally, I believe the battery may be the culprit, but not real sure.
1 Panel: CanadianSolar CS6P-270P
1 Battery: Optima Bluetop Marine Dual Purpose D34M-950
We have a Solar Charge Controller, that I assume is working properly. The LED light works without issue each night.
Our problem is with the inverter that supplies power to the sprinkler controller. It was several years old and was not supplying AC power. We replaced with a like kind PowerStream PST-INV1224-60Hz 24Vac True Sine Wave Inverter. When connected to the system, we get a solid 12V DC power in, but 0 AC power out. The inverter does not trigger "on". When I connect the inverter to my car battery (as requested by PowerStream), the inverter hums and provides AC power out.
I'm at a loss and not real sure where to turn or who to call. Spoken with a few electricians who claim it's not an electrical issue since we can verify 12V DC in. It's not an inverter issue since I can verify it works properly when connected to the car. So that leaves me with wondering if it's an incorrect battery. One of our homeowners replaced it with the current battery and we are unsure what battery was there to begin with. Any ideas if the battery could be the problem and what type of battery we need to fix this?
