How to choose a Solar Charge Controller

How to choose a Solar Charge Controller

In an era where alternative energy sources gain more ground, it is wise to learn about them in order to make good use of them in order to cut the costs of the regular means and contribute more towards being environment-friendly. One of these is solar power, which can be utilized via photovoltaic systems. These are battery-based, so choosing an appropriate charge controller is a key factor to an efficient and durable solar kit. What it does is help in protecting your batteries from unwanted damages, replacements, and other costs, as well as ensure that they are properly, fully and safely powered.

Arduino Solar Charger Controller

Arduino Solar Charger Controller

This new fully integrated solar charger is perfect solution for those wanted to utilize solar panel energy. If you plan to keep your solar energy in battery, this is the right charger to use. Capable of charging Lead Acid battery up to maximum 10A and control load of maximum 10A too. This charge controller is engineered to be durable and high efficient.

The charge controller continuously maintains the correct charge level on a 12V or 24V lead acid type backup battery, such as the 12V 7Ah battery pack, and ensure a seamless power transistion to battery power when needed. Also the charge controller allows maximum solar array current to charge into the battery, and the on board temperature sensor adjusts the charging rate based on ambient conditions.

The control circuit uses a microcontroller with intelligent control system. Charging mode uses PWM (Pulse Width Modulation) for high efficiency. Boost, recovery, and float charging are managed very easy being automatically along with the built temperature compensation to maximize battery life. The battery discharge rate is very accurately controlled, and the over-discharge voltage is continuously modify by the battery discharging rate curve.

Overload, external and internal short circuit, reverse polarity, PV panel reserve current, over charging and discharging protection of course are all built-in. In the event of short circuit or overload condition, the system will be always protected and remain 100% undamaged. Front panel LED indicators show status, and several different working modes may be set by user. It comes with English version of Getting Started Guide in the box.
