1、the suitable working temperature of 15~20℃

2、the solar battery connection method is: the solar battery positive and positive, negative and negative connection. This will double the amount of power in the solar cell, and the voltage will be the same as that of a solar cell. Solar battery pole must not short circuit (meet).

3、 for the new installation or repair after the first charge of the solar battery, a long time to charge, for the initial charge, should be charged according to the rated capacity of 1/10 of the current. Before installation, you must measure whether the battery is sufficient. If the power is insufficient, please charge the battery in a sunny place for more than 8-16 hours or use AC power to fully charge the battery. Over-discharge charging should be strictly avoided. When normally charging with alternating current, it is best to use graded charging mode, that is, constant current equalization of large current is used in the initial charging period, and then the conventional constant voltage float charging mode is used after charging to the equalization voltage and constant voltage for a certain time.
