Frequently Asked Questions
What should be noted when connecting the 50A DC-DC charger to solar panels?
"The maximum solar panel input voltage for the 50A DC-DC charger is 50V, and the maximum input power is 660W. Therefore, ensure that the maximum power of the solar panels you connect does not exceed 660W, and the maximum voltage of series or parallel connections does not exceed 50V.
The upgraded version includes a Solar Adapter Cable. Remember to use this accessory to complete the connection between the solar panel and the charger after connecting a single solar panel."

How do I disable the "Solar Low Current Shutdown" mode on the 50A DC-DC charger?
The product comes with an automatic "Solar Low Power" shutdown feature for solar power. If you want to disable this feature during use, you can purchase the BT2 Bluetooth module. After connecting it with DC HOME/RENOGY ONE, you can disable this feature through the terminal device.
What size generator is needed to work with the 50A DC-DC charger?
The charger is connected between the vehicle's main battery and the auxiliary (house) battery. The main battery primarily gets its power from the generator. To ensure efficient charging, the input energy from the main battery side must be sufficient. Therefore, the generator specifications for charging the main battery should be at least 1.5-2 times the charging current of the charger, meaning the generator should be rated at 75A-100A.
