SYMPTOM 2. BATTERY VOLTAGE IS TOO HIGH
• First check the operating conditions to conrm that the voltage is higher than
specications.
• Check that the proper battery charging algorithm (program) has been selected by
DIP Switches.
• Check that all wire connections in the system are correct and tight.
• Disconnect the PV array and momentarily disconnect the lead from the BATTERY
positive terminal BAT+. Reconnect the battery terminal and leave the PV array
disconnected. The Green charging light should not be lit. Measure the voltage
at the PV array terminals PV+ and PV- (with the array still disconnected). If
the Green charging light is on or battery voltage is measured at the PV array
terminals PV+ and PV- , the controller may be damaged.
