| ▼ Background |
A trend of photovoltaic industry is that 1500VDC system will be in place of nowaday standard 1000VDC system. Higher-voltage systems enable longer strings, which allow for fewer combiner boxes, less wiring and trenching, and therefore less labor. MORNSUN recently released new 15W and 40W power supply modules, PV15/PV40-29Bxx series, which provide 200-1500VDC input voltage, high isolation voltage of 4000VAC and that can significantly be used at high altitudes up to 5000m. |

| ▼ Application of PV Combiner Box |
|
Above is the illustration of PVxx-29B24 used in PV combiner box. 1. PVxx-29B24 series get power directly from solar arrays and offers an isolated 24VDC voltage to monitoring circuit. 2. F0505S-1WR2 offers an isolated 5V voltage to the Hall sensor, ensuring safety isolation between high and low voltage; 3. B0503XT-2WR2 offers an isolated 3.3V voltage to MCU power supply; 4. High isolated transceiver module TD501D485H is suggested for communication circuit, which can eliminate electromagnetic interference and the influence of ground loops. |
