Sell Solar controller off-grid all-in-one photovoltaicpower generation system charger 500W sine wave solar all-in-one machine best price

This product is a single all-in-one machine, does not include solar panels and batteries. The solar panels and batteries need to be prepared by themselves. The 12V all-in-one machine should be equipped with 18V solar panels. The 24V all-in-one machine should be equipped with a 36V solar panel. When purchasing, you must see if the voltage of the all-in-one machine matches the voltage of the solar panel! Otherwise, the all-in-one machine will be unusable or damaged! Note on battery selection: This all-in-one machine can be equipped with 12V batteries (multiple batteries can be connected in parallel, but must be batteries with the same capacity and brand, and old batteries that have been dismantled cannot be used) or with 12.8V iron-lithium battery packs (note 11.1V ternary batteries Cannot be used, lithium batteries cannot be connected in parallel) Correct the 220V AC output can not be used in headlamps, flashlights, LED lamps with resistance-capacitance circuits, if you use the above, please choose the correct all-in-one machine All-in-one machines of different voltages are equipped with components of different voltages. Be sure to understand clearly before using them! Controller parameters: Working voltage: 12V Maximum input current: 15A High temperature protection: 60 degrees -70 degrees DC output: 5V/1A AC output voltage: 110V/220V Rated output power: 300W-500W
