Product Description

Nominal Battery Voltage: 12V or 24V Auto select

Maximum Charging/Load Current: 30A
Product Information:

The Solar Charge Controller is a Micro-Controller Unit(MCU) based digital controller which will charge your battery in a healthy Pulse Width Modulation(PWM) 3-Stage mode . Bulk, Equalization, and Float Charging. The LCD indicates the level of the Battery and charging status. It automatically disconnects the load when battery is low. The load/light can be controlled in a dusk-to-dawn mode with very accuracy. It automatically connects the load at sunset and disconnects at sunrise. This feature is very useful for 12/24V DC solar lighting purposes. The controller also has user-friendly LCD indicators for Solar Charging status, Battery status, and Load status.

PWM Solar Charge Controller Features:



·MCU controlled digitally accurate device with 12V/24V auto distinguish

· State of Charge, Battery Level Indicator, Load status indication via LCD

· Protects your batteries from Overcharging or Over Discharge, thereby increasing their working life

· Charges battery in PWM Control 3 Stage - Bulk, Equalization, and Float Charging

· Prevents Reverse Current to Solar Panels during Night time

· Easy to install, lightweight, and very compact in size

·Dusk-to-dawn controlled loading mode

·Short Circuit and overload protection
Technical Information:

This is a MOSFET based design which has very negligible voltage drop which means the loss is very Low, ideal for solar applications. Since the drop is less, the losses are negligible so the efficiency achieved is > 99.5%.This is a micro-controller based charger, the micro-controller will sense the battery full charge voltage and will cut-off the battery when it reaches full charge. It will reconnect the battery if the battery drops to a preset level. The charger will also disconnect the panel from the battery; this is to avoid the reverse current flow from the battery to the panel during night. Moreover, if you connect the panel reverse, the micro-controller will not switch on the charger; similarly if you connect the battery reverse, the charger will not function. Battery reverse, panel reverse protections are implemented in the design. In all the above cases, the circuit will not damage and there will not be any current flow from the panel or battery. Two stage higher voltage regulators are incorporated in this design to withstand open circuit voltage of the panel.

Introduction of Solar Converter

Solar Converter is a Innovative way to make solar cost affordable to masses and change lives. Solar Converter is for those who have already invested in Inverters or UPS. Solar Converter is a product which can converter any Inverter or UPS into a solar system. This product will preserve your investment and make you a proud owner of renewable energy generating system.

Solar Converter

We offer Solar Converter cum Solar Charge Controller for existing inverters. If you own an inverter system then by connecting our Solar Converter you can convert your existing non Solar Inverter into a Solar Inverter.

Why Solar Converter?

We offer Solar Converter cum solar charge controller for existing inverters.

If you own an inverter system then by connecting our Solar Converter you converts your existing non solar inverter system into a solar inverter. This gives priority to solar charging.
