How to choose a portable solar controller for your PV model? Frogbro tell you…

The following factors should be considered when buying a charge controller:

• Your budget

• Lifespan of the technology

• Climate where your system will be installed: Certain charge controllers operate better in colder climates.

• How many solar panels you have and how high your energy needs are

• Size, number, and type of batteries you’re using in your system

These factors all interact in complex ways that can be challenging to implement effectively. However, there is a clear process for determining which charge controller is right for your application.

What are solar charge controllers?

The charge controller in your solar installation sits between the energy source (solar panels) and storage (batteries). Charge controllers prevent your batteries from being overcharged by limiting the amount and rate of charge to your batteries. They also prevent battery drainage by shutting down the system if stored power falls below 50 percent capacity and charge the batteries at the correct voltage level. This helps preserve the life and health of the batteries.

How do solar charge controllers work?

Regarding “what does a solar charge controller do”, most charge controllers has a charge current passing through a semiconductor which acts like a valve a to control the current. Charge controllers also prevent your batteries from being overcharged by reducing the flow of energy to the battery once it reaches a specific voltage. Overcharging batteries can be particularly damaging to the battery itself so charge controllers are especially crucial.

What is overload production function?

Overload protection: Charge controllers provide the important function of overload protection. If the current flowing into your batteries is much higher than what the circuit can deal with, your system may overload. This can lead to overheating or even fires. Charge controllers prevent these overloads from occurring. In larger systems, we also recommend a double safety protection with circuit breakers or fuses.

What is low voltage disconnects function?

Low voltage disconnects: This works as an automatic disconnect of non-critical loads from the battery when the voltage falls below a defined threshold. It will automatically reconnect to the battery when it is being charged. This will prevent an over-discharge.

What is block reverse currents function?

Block Reverse Currents: Solar panels pump current through your battery in one direction. At night, panels may naturally pass some of that current in the reverse direction. This can cause a slight discharge from the battery. Charge controllers prevent this from happening by acting as a valve.

Do you always need a solar charge controller?

Solar charge controllers play an integral role in solar power generation systems, making them safe and effective. You can’t simply connect a solar panel directly to the battery and expect it to work. The solar panel output exceeds its nominal voltage. For example, a 12v solar panel may output up to 19 volts.

Solar charge controllers are not an optional component to improve efficiency. They are an absolute necessity that makes charging solar cells possible.

What's your payment term?

Portable generators provide electricity by running a gas-powered engine that turns an on-board alternator to generate electrical power. Power outlets on the unit allow you to plug extension cords, electric-powered tools and appliances into it.

How long is the delivery time for orders?

If we have inventory of goods, the delivery time will be within 7 days after receiving the payment. The delivery time for goods without inventory will be between 25 and 35 days.
