I STILL have a working Grumman Sunstream water heater and it's running 24/7 since I replaced the 80 gallon water heater.

I purchased a C-30 controller - it's coming in the mail. The plumber who installed the new water heater did a perfect job of installing to the console, but something changed, the console is on all the time, trying to collect. I'm very concerned as it's been 2 weeks and all the troubleshooting is getting me no where. Thankful for a contact with someone who can help. I AM ON KAUAI a little Hawaiian island. so it's slim pickings. Thanks Lynne

I know you're probably looking for someone who has one and who can help you out I know the principles behind it but there's so much information you left out that I'm trying to piece it together.
I hope this will help.

If you do not have the original owner's manual and if it is a CF 100 then
you have to join this site in order to download the PDF document your going to have to give a credit card I think it's a free trial I'm not a member so cannot recommend it. But the site is legitimate.

If you could perhaps make a block diagram of your specific setup; solar panel battery, Maximum power point tracking (MPPT) etc. then I would be happy to assist you.
