If the inverter charger is connected to an AC Power Supply (AC Generator) and the generator can automatically start/stop, it is recommended to connect the generator to the Dry Contact Relay Terminal Block with a signal cable.
When the voltage of the inverter charger is lower than the set voltage in program 96, the inverter charger will automatically start the generator and charge the battery while the load is supplied by the generator. When the voltage of the inverter charger is higher than the set value, the inverter charger will automatically shut down the generator.
warning

  • You can set the voltage of the inverter charger in program 96. The voltage should be set after the inverter charger is turned on. Please finish the installation of the inverter charger first.
  • Please read the user manual of the generator carefully before connection. Make sure the generator can automatically start/stop. Identify NC (normally closed contact), NO (normally open contact), and C (common static contact) of the generator and ensure signal lines are connected properly.
  • Some generators only have NC (normally closed contact) and C (common static contact) or NO (normally open contact) and C (common static contact). You can connect them on demand.
  • Do not store the inverter charger with auto gen start feature enabled. Generators exhaust dangerous fumes when running.

If your generator has an automatic start/stop function, you can connect the generator to NC, C, and NO wiring holes corresponding to Dry Contact Relay Terminal Block of the inverter charger via a signal cable.
Automatic Generator Start
If your inverter charger uses the DC Generator as the power supply and the DC Generator can automatically start/stop, you can connect the DC Generator to the inverter charger via the signal line. The inverter charger will automatically start and stop the generator according to the voltage you set. The signal line is connected in the same way as the AC Generator.
warning

Working

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.
Working - Step 1

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.
Working - Step 2

When the battery is fully charged, the CHG indicator is solid green.

warning

  • If the AC/INV indicator and CHG indicator do not light up as described in this guide, but the power supply equipment (batteries and AC input source) is operating normally, the inverter charger needs troubleshooting. Please contact our customer service through renogy.com/contact-us/.
  • You can set the charging current with program [11]. If the default settings do not apply to your installation, you can set them in the custom (battery) settings (as recommended by the battery manufacturer), or via the DC Home app.

Under normal conditions, the inverter charger FAULT indicator and the wired remote control ERR indicator will not light up.
Working - Step 3

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.
Working - Step 4

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/.
Working - Step 5

Power Off

Main Switch

The ON indicator of the wired remote control, the screen, and indicator lights go off when the inverter charger is powered off.
Power Off - Method 2 - Wired Remote Control

Overcurrent Protection

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.
warning

  • Risk of electric shock! Turn off the inverter charger and the power devices connected to it when the circuit breaker is reset.
  • Please wear proper protective equipment and use insulated tools during operation. Be careful when touching bare terminals of capacitors as they may retain high lethal voltages even after power is removed.
  • After resetting, please install the Top Plate back to the inverter charger.

Turn the two upper panel screws counterclockwise by hand or a Phillips screwdriver, and remove the Top Plate.
Overcurrent Protection - Step 1

When the AC input current exceeds 40A, the Input Circuit Breaker will automatically pop out. Press to reset it.
Overcurrent Protection - Step 2

When the AC output current exceeds 30A, the Output Circuit Breaker will automatically pop out. Press to reset it.
Overcurrent Protection - Step 3

Maintenance

For optimum performance, it is recommended to perform these tasks irregularly.

  • Ensure the inverter charger is installed in a clean, dry and ventilated area.
  • Ensure there is no damage or wear on the cables.
  • Ensure the firmness of the connectors and check if there are any loose, damaged or burnt connections.
  • Make sure the AC/INV indicator, CHG indicator and FAULT indicator are in proper condition.
  • Ensure there is no corrosion, insulation damage, or discoloration marks of overheating or burning.
  • If the inverter charger is dirty, use a damp cloth to clean the outside of the device to prevent dust and dirt from accumulating. Before the inverter charger is powered on, please make sure it is completely dry after cleaning.
  • Make sure the ventilation holes are not blocked.

warning

  • Risk of electric shock! Make sure that all power supplies are turned off before touching terminals on the inverter charger. Please wear proper protective equipment and use insulated tools during operation. Be careful when touching bare terminals of capacitors as they may retain high lethal voltages even after power is removed.
