Product Detail

220V Controller BIPV Off Grid Solar Energy Systems 10 In 1 Combiner Box . Applications Suitable for factories, farms, cell phone towers, schools and so on at the areas without electricity. . Installation requirement There is enough area to place solar modules .Advantages and disadvantages Advantages no need to be connected to grid, suitable for no-power areas; it can supply power stably and steadily; maintenance-free and easy to install. Disadvantages the system should use energy storage devices: batteries, which should be replaced at regular time intervals, at present, a high quality colloid storage battery should be replaced in 3-5 years. . Capacity designing Designing the system according to the total power of electric equipment,daily electricity consumption, and day/night electricity consumption proportion etc. Note: if daytime electricity consumption increases, we can cut down battery cost, then the total cost will be also cutted down. - - - - 11KW off-grid system | NO. | Item | Type | Quantity | Unit | Unit Price | Total Price(USD) | | Equipment | | | | | | 1 | Solar modules | 250W | 44 | pcs | | | 2 | Combiner Box | | 4 | unit | | | 3 | Brackets for panels | | 1 | set | | | 4 | Controller | 48V | 1 | unit | | | 5 | Inverter | 20KW | 1 | unit | | | 6 | Battery | 12V/250AH | 60 | pcs | | | 7 | Brackets for batteries | | 1 | set | | | 8 | Connectors | | 50 | set | | | 9 | Cable tube | 25 | 240 | m | | | 10 | Cable 1 | 10mm | 240 | m | | | 11 | Cable 2 | 4mm | 240 | m | | | 12 | Total | | 0 | Project data: Solar module capacity: 11KW | Battery capacity: 140KWH | Output power of inverter: 20KW | Input voltage of inverter: 48VDC | Efficiency of inverter: 92% | Power factor: 0.99 | Designed system life span: 15years(batteries replaced every 3-5 years due to real situation) | P.S.: 7 days's charging for 3 days use (24 hrs/day).
