Harvest solar air conditioners were installed in Thailand recently.
“Hybrid control box” was included in each solar air conditioner system. Each solar air conditioner can work 15 hours per day 100% by solar panels. Power supply will be switched to grid power automatically upon low battery. After voltage of battery bank rise up, the power supply will be switched back to solar energy automatically.
The “hybrid control box” can take most advantage of solar energy, meanwhile, it can help end users to enjoy air conditioning 24 hours per day without too much initial investment on solar panels and battery bank.
