Inverter/Charger Working Principle & Applications

Inverter Split-Phase Output Terminal Description

Tips: Daily Maintenance of Power Inverters

1. Check whether the load is within the rated power, the voltage range and current of the power inverter.

2. Maintain your inverters properly and regularly: use wet cloth to wipe out the external dust and dirt of the inverter; tighten the screw of the DC input terminal; use high-pressure air gun to clean up the internal dust and foreign matter.

3. Inverter must be turned off when cleaning and maintenance is carried out.

4. In the process of maintaining inverters, it is best to do the following:

First, periodically check whether the line part is intact. If there is something abnormal, it is necessary to timely replace.
Secondly, in the process of using the inverters, it is necessary to stop and check immediately if there is a problem. Only after the problem is solved, can the inverters continue to be used.
Thirdly, in the process of maintenance, the failure of unknown cause should be recorded in advance, and then ask the manufacturer to deal with it.
Fourth, when cleaning inverters, it is necessary to use soft cloth for scrubbing, not to use too much friction scrubbing tools.
Fifth, periodically check whether its heat sink and seal are blocked or not. If so, dust should be disposed of in time.

4000w inverter charger

Can your inverter charger output split phase?

From: Eric W. | Date: 04/12/2019

ATO Responded

Our inverter charger is available with 240V AC input to 120/240V AC split phase output.

Easy to install, and works great.

This inverter charger was purchased to replace the damaged one in my RV. The old one was 2000 watts, and I would need an upgrade one - 4000w inverter charger - for the batteries are always fully-charged and powering more devices on the road trip. This was easy to hook up, just disconnecting the wires from the old unit and connecting the new ones. So far, works great.
