ARI-450 Charge Controller can take 2 solar panels. ARI-750 Charge Controller can take 4 solar panels. Our systems are designed to automatically allow both or either wind or solar without issue. The smaller turbine's charge controller is designed for up to 2 solar panels, but the larger turbine's charge controller is designed for up to 4 solar panels. This information might influence your decision:
750W 48V, it can go up to 60x15=900W (see the manual, pg 22, section 6.2.3 Charge Controller, table)
750W 24V, it can go up to 30x30.5=915W
500W 12V, it can go up to 35x15.5=542W
500W 24V can go up to 18x30.5=549W
We sell solar panels in pairs, because they are packaged in pairs, but the system will handle up to the above combined limits.
Solar panels have pre-configured set voltages. The solar panel voltage coming into the charge controller must equal the voltage of the ARI wind turbine/charge controller, which you own. Example: If you own a 48 volt ARI wind turbine, you can use 48 volt solar panels connected in parallel, or 12 and/or 24 volt solar panels connected in series adding up to 48 volts.
We recommend you to purchase 2 or 4 solar PV panels to take advantage of our ARI Solar Wind charge controller, as well as to give you backup complementary energy, just in case you have no wind for some days.
Solar Panels: With our solar panels, Two 12 volt panels may be connected in series to create 24 volts or four to make 48 volts; or any other arrangements of series and parallel to meet your needs. They are ARI branded.
