Solar pannels problems

[Davidtastic]

Hello

Can someone please help me. My solar pannel box upstairs was making a big rattling noise so I took the cover off and noticed the pump was vibrating as if there was air trapped so I vented the pump and the noise continued. I then opened the tank in the box and noticed it was very low on glycol so I topped the tank up. I then turned the pannels back on at the switch and there seems to be nothing working. There are no lights to say anything is happening.

Thanks Dave

Ran the pump dry and fried it? Just a guess.

Probably a pretty good guess!

are there any fuses to check?

doesn't have to be the case but some panels come with diodes built in, check and see if they are burnt and replace them (just my guess)
