Eak sun hours for various geographical areas is listed in the above section. Solar panels can be wired in series or in parallel to increase voltage or amperage respectively, and they can be wired both in series and in parallel to increase both volts and amps. Series wiring refers to connecting the positive terminal of one panel to the negative terminal of another. The resulting outer positive and negative terminals will produce voltage the sum of the two panels, but the amperage stays the same as one panel. So two 12 volt/3.5 amp panels wired in series produces 24 volts at 3.5 amps. Four of these wired in series would produce 48 volts at 3.5 amps. Parallel wiring refers to connecting positive terminals to positive terminals and negative to negative. The result is that voltage stays the same, but amperage becomes the sum of the number of panels. So two 12 volt/3.5 amp panels wired in parallel would produce 12 volts at 7 amps. Four panels would produce 12 volts at 14 amps.

Sdp-40kw Sandi pure sine wave series inverter is one of the most advanced dc to ac conversion products in the world, it has the main advantages of high quality sine wave ac output, microcomputer control, humanness design, and it is simple, stable, no noise and no pollution. It is suitable use for areas without electricity, vehicles, ships, solar energy, wind turbine etc. The inverter can also supply ac voltage to all kinds of power tools, air conditioners, electric motors, refrigerators, fluorescent lights, televisions, electric fans and other power supply. The inverter output waveform is pure sine wave; this kind of ac power is suitable for most industrial electronics and home appliances, the power supply features much better than other modified sine wave and square wave. Technical features: 1, two kinds of start mode: reduction voltage start and variable frequency start. Customers can set start mode according to the nature of their load. 2, the output frequency can be set, this function is very convenient for customer. 3, the output voltage can be set between +20 % to -40 % of rated voltage. It¡¯s a great convenience to users. 4, the dc input voltage range can also be set. Over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point all can be set via the lcd panel. Convenient for increasing or reducing the quantity of batteries, photovoltaic modules also can be used flexibly. Standard export honeycomb carton packing with pallet
