REGO 12V 3000W Inverter Charger combines an inverter charger with an automatic transfer switch into one complete system. Featuring a 3-stage battery charging mode when connected to the utility AC power, the inverter charger can meet powerful needs as well as charge your battery bank. As a power supply, it is capable of producing cleaner, smoother, and more reliable electricity to address your diverse needs.
The inverter charger is equipped with a 30A transfer relay switch that switches between the charging and the standby mode depending on availability of AC input power. If AC is present, the transfer relay bypasses up to 30A of the incoming AC power through the inverter to power the AC loads on the inverter's output. Simultaneously, the inverter charges the battery up to 75 Amps. In the event that AC inverter charger gets disconnected, and the inverter will power the loads through the battery bank.
The ON indicator of the wired remote control and the AC/ INV indicator of the inverter charger flash green when the inverter charger is powering loads from the battery.
The ON indicator of the wired remote control and the AC/INV indicator of the inverter charger are solid green when the inverter charger is powering the loads through an AC Input Source, and when the inverter charger starts to charge the battery at the same time. The CHG indicator flashes green.
When the battery is fully charged, the CHG indicator is solid green.
Under normal conditions, the inverter charger FAULT indicator and the wired remote control ERR indicator will not light up.
If the FAULT indicator of the inverter charger and the wired remote control ERR indicator flash red, and the buzzer sounds at the same time (0.5s), it means warnings are provided by the inverter charger.
If the FAULT indicator of the inverter charger and the wired remote control ERR indicator is always in red, and the buzzer sounds long, it means that the inverter charger needs troubleshooting. Please seek help through renogy.com/contact-us/.
Press the main switch of the inverter charger to "OFF" to turn it off.
The screen and indicator lights turn off when the inverter charger is powered off.
When using a wired remote control, press the button on the wired remote control to turn off the power.
The ON indicator of the wired remote control, the screen, and indicator lights go off when the inverter charger is powered off.
The inverter charger is integrated with two circuit breakers which ensure that the inverter charger keeps operating even when the input/output stops working. When the input/output circuit breaker is activated, a manual reset is required to resume operation.
Turn the two upper panel screws counterclockwise by hand or a Phillips screwdriver, and remove the Top Plate.
When the AC input current exceeds 40A, the Input Circuit Breaker will automatically pop out. Press to reset it.
When the AC output current exceeds 30A, the Output Circuit Breaker will automatically pop out. Press to reset it.
For optimum performance, it is recommended to perform these tasks irregularly.
