PWM Solar charge controller (240V-50A)

Applying with various types of batteries Multiple protect functions Automatic recognition of input voltage

No .1  General  Description 

The solar charge controller is the intelligent power with integration of controlling . It can store electrical power generated by the solar panels into the storage battery.

The controller not only has perfect appearance, LCD display and convenient operation, but also has over-charge protection, over-voltage  protection, over-hot protection, under-voltage protection, pole-confusion protection for storage battery and automatic dump-load function. The controller is adopted the constant voltage charging mode-PWM, and it has high reliable and safe operation, high efficiency, long service life functions. What’s more, it adopts the American origin Micro-controller as a control core component with reliable. And the power parts of an apparatus adopt the import component, too.

No .2   Design characteristic.

1  PWM mode off-overload: When solar panels exceeds the needs of the battery and inverter output, the control system must let out the superfluous power by discharging. The ordinary way is connecting the whole discharging, but the battery perhaps is not full while the power deplete on discharging, so it costs much waste. Someone may discharge by stages .the more stages have, the higher efficiency is. But it is only five or six stages at most. The effect is also out of expectation. In our products, the control-inverter is adopted the constant voltage charging mode-PWM. it can achieve to thousands of  stages. So we are sure to make the storage battery voltage be on the floating charge voltage all the time and make full use of the electrical power and prolong the service life of the battery.

2  high Reliability:  Perfect protections, it contains over-charge protection, over- voltage protection, low-voltage protection, over-hot protection, short-circuit protection, over-discharge protection, reverse connection protection, over-voltage for automatic brake protection and PWM–mode discharge.

3  LCD display the battery voltage and charge current: You could look at  magnitude of the solar panel charge current and storage battery state, then accommodate the magnitude and time of the user-load based on battery voltage. It makes the products possess of humanized design. 

4. LED of “system” is indicate device working status; LED of “battery” is indicate battery capacity whether be normal.

5.  digital intelligent control:  The machine is adopted Microcomputer chip as its core component to ensures accurate control, which also makes the peripheral circuit structure simply. It has agile control way and control strategy with high function and reliability.

No. 3  Functions

1. Charging and control:  When the solar panels exceeds the needs of the battery and inverter output, the machine must let out the superfluous power with PWM control mode by discharging. we are sure to make the battery’s voltage level off the floating charge voltage all the time and make full use of the electrical power and prolong the service life of the battery.

2. Automatic regulate voltage: The equipment output constant power and automatically when the voltage wave between low-voltage and over-voltage in the storage battery and the loads vary in the rated capacity.

3. Over-voltage protection: When the voltage is above the “over-voltage ”, the machine should proceed PWM dump load to solar panel so that down the voltage output automatically. And battery LED will lighting in red . If voltage down to normal range, the led will shutdown.

4. Low-voltage protection: When the voltage is above the “over-voltage ”, the machine should proceed PWM dump load to solar panel so that down the voltage output automatically. And battery LED will sharking in red . If voltage down to normal range, the led will shutdown.

5. short circuit protection: If the DC output is short circuit, The machine will shut off by inner fuse automatically. 

6. Battery reverse connection protection: The machine has Perfect battery reverse connection protection. If you connect the anode and cathode reverse, the Intestine fuse will burn out automatically to protect the storage battery and equipment away from destroyed. But it is forbiden to connect inversely.

No. 4 Use Environment

1  Let the machine work in the dry, clean and well ventilated environment.

2  Keep away from the point-blank, insolation, drench, humidity and acid mist environment.

3  Avoid from dust environment when used.

4  The distance should be above 0.5m between the machine and the battery .

5  It is not allow to use it in the flammable and easy blast environment, be care of blaze and scintilla.

6  Environment temperature:  -100C ~ +400C.

7  The max humidity is under 85%. (25°C±5°C).

8  If you use it over 2000m altitude, the output power will decrease 5% while the altitude increases each 1000m.
