Two working way for your choice:Before order, need confirm us for which working way you want.

1,Battery power priority: First use the battery power,When battery power is lower, inverter will automatically use City power(bypass function)to take the load, do not charging the  battery..When battery voltage rises,inverter will switch to use the batteries power to supply the power automatically..,Mostly use in solar off grid power systems.                                                                                                   

2,The city power priority, First use the Mains power to take the load and charging the batteries at the same time,when it has no city power, inverter will automatically switch to battery power to supply the load (UPS function),mostly use in back up power supply.
