500 Amp hours of batteries, fuse blocks and solar panel controller, with 4 x 180 watt panels. Each panel is capable of 8 amps on a bright day.
Outback solar controller. This controller will deliver up to 33 percent more power than what is output by the solar panels. With 32 amps of panels I have seen upwards of 42 amps output with this controller. The green wire is a battery temp sensor to keep the controller from cooking the batteries.
Fuse and grounding blocks for the solar panels. Each panel is fused with a 10 amp fuse. Then they are routed into a 40 amp fuse into the controller. A 60 amp fuse is used from the controller to the batteries.
One 200 amp fuse is for the 1000 watt inverter and the other is for the power block below. This is to prevent accidents from occurring.
Fuse blocks for users to attach their devices to the battery pack. This has a 32 foot number 2 gauge wire to reduce any power lost.
This allows for a clean connection to the battery pack. Each connection can handle any car fuse so a user can select the correct amperage. The plastic lids keep any exposures for shorts to a minimum.
