My batteries are mounted on the outside wall and with these winter temperatures hitting the minus figures.
I am on the IOG Tariff and currently the batteries charge at a charge rate of 100% but I would like to reduce the overnight charge rate so that the charge period is stretched, hopefully resulting in the batteries maintaining their temperature above zero degrees.
Could anyone give me advice as to which Wonder Watt setting I could use to set a charge rate of say 40% initially so that I can find the best charge rate for the batteries to charge over most of the IOG night tariff.
Many thanks in advance.
