The 12v solar panel kit from Grape Solar is a high-performance 400-watt system. These are four rigid and strong solar modules with an output of 100 watts per module.
the 400W 12v solar panel kit as a battery charger and many more applications.
call it the Grape Solar 400W Off-Grid Solar Panel Kit. (Or the GS-400-KIT.)
solar kit performs very well under low light, shady and cloudy conditions.
The 12 volt solar panels can withstand heavy snowfalls and strong wind loads. This is because of the use of low iron tempered glass. This is for enhanced stiffness and high impact resistance.
1) Four pieces of Polycrystalline 100 watt solar panels. It can deliver 400 Watt peak output per hour.
A 40 Amp Comet PWM charge controller. With this controller, you can add one more
panel with extra cables to give an output of 500 watt.
3) An 1800-Watt Grape Solar PurePower Inverter with two outlets and 1 USB port.
Wire for charge-controller-to-battery.
MC4 parallel cable sets, 4 inputs and 1 output on each.
A pair of 15-foot MC4-to-MC4 cables.
MC4-to-bare cable pair.
Four 10 amp inline fuses.
5) Also a user’s manual.
the four 100 watt solar panels, you get about 2400 Watts of power during peak
time. This is for 6 hours of sunshine per day.
is 100 watt X 4 panels X 6 hours of sunshine = 2400 Watt.
you take losses and non-peak performance into consideration (Minus 15%). You
can still get a fair 2400 X 85/100 = 2040 Watt per day.
the 40 watts and you get 2 Kilowatt per day
is a fair amount of cheap electricity for many years to come.

Use the pair of MC4 parallel cable sets (4 inputs and 1 output on each). This is to connect the four solar panels to the pair of 15-foot MC4-to-MC4 cables.
Then use the red/black 6” MC4-to-bare cable pair to connect the 15 foot MC4 to MC4 cables to the charge controller. The bare ends of the pair go into the charge controller.
You have to connect the inline fuses to the positive lead of each 100 watt solar panel.
Setting it up is quick and easy.
