Gebosun Solar Street Light Controller Protection Mechanism

Charging over-temperature protection mechanism	When charging, if the internal temperature of the controller exceeds 90°C, charging will stop and will not resume until the temperature drops to 85°C.
Open circuit protection mechanism	When the light is on, if the LED light board is open, the output end will be boosted to 32V to maintain a constant voltage state, and the applet will display LED OPEN
Over discharge protection mechanism	If the battery voltage is lower than the over-discharge point during output, the output will stop and the applet will display BAT LOW. The protection will be removed only when it is daytime again.
Output short circuit protection mechanism	When the output is short-circuited, the output will stop and the applet will display LED SHORT. The protection will be removed only when it is daytime again.
Maximum charging current protection mechanism	During charging, if the photovoltaic panel power is too large and triggers the maximum charging current, the system will maintain the maximum current constant current charging and will not increase.
Overcharge protection mechanism	If the battery voltage reaches the overcharge voltage point, the constant voltage charging mode will be maintained until the current reaches 0, and the applet displays BAT FULL

Solar Charge Controller Frequently Asked Questions

What Is Solar Charge Controller?

A solar charge controller is a device that regulates the flow of electricity between solar panels and a battery bank in a solar power system. It ensures the batteries are charged properly, preventing overcharging and extending battery life. Essentially, it acts as a regulator to ensure the battery receives the correct voltage and current from the solar panels.

Can I mix different panel voltages?

Yes—dual-MPPT supports arrays up to 150V each on our MPPT solar charge controllers.

What is the purpose of a solar charge controller?

What is a Solar Charge Controller? A charge controller or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery.

How many rainy days can it handle?

Up to 7 days with LiFePO₄ batteries, thanks to efficient solar charge management.

Can I customize charge curves?

Yes—upload profiles via app for optimal solar battery protection.

Are firmware updates secure?

Digitally signed and encrypted (TLS 1.2+) for safe remote monitoring solar controller updates.

What happens during a fault?

PV input shuts off, alerts are sent, and events logged—robust solar charge management in action.

Can it integrate with SCADA?

Yes—Modbus/RS485 and MQTT APIs ensure compatibility.

How do I mount it?

Options include brackets, DIN-rail, or pole-box kits.

What’s the warranty?

5 years on electronics, 2 years on mechanical parts.

Can you assist with sizing?

Yes—free assessments optimize your solar power optimizer setup.

Do I need a solar charge controller?

A solar charge controller regulates the electrical current to prevent the battery from electrical surges that can damage it and reduce its lifespan. A solar charge controller is essential if your PV solar array feeds a battery bank. If you are on a grid-tied system, you probably don't need a solar charge controller.
