Q: if I need to add controller between solar panels and inverter?
A: no need, as our inverter already set up controller inside machine. just connect solar panels in our inverter directly.
Q: why customer need use generator, to charge our ac inverter?
A: the generator is AC output, this should be connect to our AC power cord, not battery, means generator is like home power AC source, and because generator's AC source quality is bad & dirty, will damage appliances if connect generator & appliances directly for a long time, through our pure sine wave power inverter, inverter will transfer the power to pure power
Q: I have received my item okay. There are to 12v inputs on the back of the unit, do you have to wire them both up or just use one set for one bank of batteries?
A: Just use one set is ok, if you want to use big watt, you can use both so as to balance the electric amps.

Q: Can I use this inverter to charge my battery on 110v home grid?
A: No, this battery charger function on split phase version is only for 220v home grid power, can not for 110v.
Q: The battery charger does not seem to work，how do I check it?
A: To charge the battery, need to confirm the following situations:
1.right dc voltage, for dc12v inverter the voltage range is 10.5-15V；for dc 24v inverter, the voltage range is 21-30V；for dc 48v inverter, the voltage range is 42-60V.
2.AC INPUT must connect to the home grid, and the home voltage and frequency must be the same as the inverter's, also should be pure sine wave.
Q: What the volt adjustment is for on the battery charger it the small white round switch with #o to 9 so please what dose it do?
A:On the volt adjustment, you can adjust this to match your battery voltage, "1" is the lowest battery voltage, and "8" is the highest battery voltage,(0 and 9 do not have charging function), you can begin from 1, then 2, then 3..., until the right number that suit for your battery voltage.
