Hi, I really need help, our Voltech ISC3040 has a E5 code on the dial, operating book goes to E4.
The 2x170 watts solar panels linked with 2x100 amp batteries has been working great since October 2016 but yesterday when I was up the caravan to my horror this message was on the screen.
The batteries are holding 12.6 volts but was earlier in the day, solar was pumping in 13.4 volts.
Can any one for warn me what the problem may be please.

All sorted, I rang the Voltech service, Mark was excellent in helping me sort the problem with the E5 error code.
Needed a set manual reset by removing the 2 earth wires from the mppt and counting to 20, replace and all is good.
Voltech is a Brisbane based company eager help with customer service.

I have the same issue with my controller. But, when I removed the earth on the solar side and the controller came on. When I replaced that wire, everything cut out again.
Anybody experienced the same ?
Thanks in advance.

I would star by measuring the voltages at the battery terminals, solar panel, and the inputs and outputs of the MPPT controller.
See what changes when you cover the panels with a blanket.
Connect the battery to a large load and see if that changes anything.

Start at the beginning. Disconnect the solar from the solar panels and the battery. Check your battery voltage as Dorian has stated. Wait a couple of minutes then connect your controller to the battery first. Let the controller determine the battery voltage for a minute then reconnect to your solar panels.
What make and model is your solar controller.
Most solar controllers require connection to the battery first and to solar panels second.
If it cuts out again when connecting the solar panels measure the panels voltage.
