The control panel battery charge capacity is 7.0 to 35 AH. Use 12V batteries of the
same AH rating. Determine the correct AH rating as per your current load calculation
(see Section 3.6).
Wire batteries in series to produce a 24-volt equivalent. Do not parallel batteries to
increase the AH rating. It is recommended that you replace batteries every five years.
