Hi there Dave & Jon,

Many thanks for your ideas and suggestions.

We will check out the short circuit first.

But it seems to me that maybe we have an undersized battery bank. We have 8 x 6v giving 232ah per battery, wired in series, so if my understanding is correct we only have 232ah storage.

This might be the answer.

We will check into this and I will let you know the outcome.

Many thanks for your help guy.

Janet

Hi there, we are relatively new to RE, and wondered if anyone could advise on the following problem we are experiencing.

We have a 48v system, our panels are collecting normally, and we are absorbing at 57.6v daily, we average around 110 to 160 amp hours per day. Batteries are water checked and equalised regularly.

In the evening with battery levels anywhere from 50 to 48.5v the system trips out. When we unplug our energy efficient fridge/freezer, reset and we are ok with the exception we cannot get the fridge back in without tripping the system.

Any advice or suggestion would be welcome.

Thanks

Janet Gregory
