Macon - Model MA22H - Hybrid Solar Charge Controller
It is common observation, during cloudy atmosphere power generated from solar panel may not be sufficient to fully charge the battery thereby resulting in the premature shut down of the street light in the midnight. MA22H, a 24V based hybrid system which is another quality product entirely designed, developed and manufactured by us is a perfect solution to this problem. It accepts dc from mains to keep load on if battery power is found insufficient during operation.
Many a time, even if the system is conservatively designed with autonomy, the batteries loose the power over a period of time or insolation is insufficient for days together to charge the batteries optimally and light is off prematurely. If the system is of critical nature, mains power can be automatically switched to drive the load during such emergencies. And the load will be on throughout the night uninterruptedly.
- Hybrid solution involving the mains power should not interfere in the normal charging and discharging of the battery bank.
- Mains power should not charge the battery but simply provide power to the load during night if battery fails to provide it. The very purpose of harnessing solar power will be lost if mains power charges battery.
- Mains power should not disturb the operation settings of the load. Obviously, during day time, mains power should just stay in standby mode without interfering the solar generation/charging.
- User must know if the system is running on mains power during such emergencies.
- Mains operation should not be possible if battery is not present. Else, it will be simply a mains-operated system.
- If battery is dead or absent, user should immediately come to know that system needs battery replacement. So the system should be off all the time if battery is dead or absent.
- If mains supply is not available, it should work in normal operation mode as a stand alone solar street light.
Our MA22H is designed with the view to providing such a solution and more.
The controller is accompanied with specially designed mains power pack compatible to the controller.
The controller has auxiliary output terminal where battery voltage is available during night to drive additional gadgets like surveillance devices, GPS tracker, IP camera etc. if needed.
