    Tips: General Inverter vs. UPS Inverter

    The general inverter converts ac to DC to charge and store the battery. In case of power failure, the DC stored in the battery will be converted to AC for the load to use. The primary function of energy storage inverter is to carry out the kinetic energy bi-phase transmission between ac power grid and energy storage battery. It is also a bi-phase converter, which can be compatible with all kinds of DC energy storage units, such as super capacitor banks and battery banks.

    The ups (uninterruptible power supply) inverter can provide stable power supply for communication, medical, data platform and other network systems with special demand for power supply in the case of power grid outage or unstable power supply.

    What current will inverter recharge my battery?
    I am interested in the ATO-UPSI-500.
    I would use it on a 12V DC 120 Amp-Hour Lead-Acid Deep cycle battery.
    I have 120V AC at 60 Hz.
    At what current (Amps) will it recharge my battery?

    ATO Responded
    The charging current of the battery is 20A.
    Which batteries type should select?
    Advise. And which batteries type option should select "lithium or lead acid"?
    Show this type of batteries "LiFePO4" in our inverters options.

    ATO Responded
    It can support Lifepo4 (Lithium Phosphat) battery and the battery charge current is 20A. The inverter will automatically enter the floating charging state when the battery is close to full charging. Lithium batteries can be selected. Our UPS inverter does not need to distinguish the types of lithium batteries, so customers can choose lithium batteries as long as the batteries they use are lithium batteries.
    Great 500W ups inverter
    Great 500W ups inverter! It works just like it should and with little to no noise. And installation was easy with heavy gauge DC supply cables supplied. I have been using it for two months with no problems.
