The Renogy Solar Panel Extension Cable will be able to make more space between your solar panels and the charge controller. There is multiple size choice, please choose the same size of cable for extension. And please also realize that the longer the extension, the greater the line loss. A bigger gauge will be required for longer runs.

This solar suitcase is designed for expansion, additional panels are added to the system available based on your needs and space. We suggest you add the same solar suitcase for expansion.

Only the solar suitcase included. But you can search and find a plug-and-play bundle kit including this suitcase and a waterproof Renogy Voyager 20A charger controller. You may also choose the controller according to your system, divide the total power by the battery system voltage, the current value get can be used as a reference for controller selection.

A solar panel has to be connected to a charge controller to regulate current, and a battery to store the electrical power. You will need adapter kit cables to wire the solar panel(s) and charge controller, and tray cables connecting the charge controller to a deep-cycle battery.

The suitcase is not able to charge 120V power receptacles directly. Plus a 12v battery and inverter would give the 120v output you would want. The panel would recharge the battery, the battery will store the power, and the inverter would be able to supply the 120v power that you need.

The suitcase with 2 pcs 50W Renogy high-quality monocrystalline solar panels.

The solar panels are fully waterproof with IP66 class. It will be able to work on rainy days and applicable to a wider range of scenarios, such as marine, yacht, etc. But we recommend you to use it with a waterproof charge controller, since water into the regular controller may damage the internal circuitry. You can search and find a bundle system including this suitcase with a waterproof Renogy Voyager 20A charger controller.

Solar panel performance may be hindered for a number of reasons. Most commonly environmental conditions such as indirect sunlight, temperature rise, cloudy sky, and dirt and stain build up on the top glass will cause a reduced power output. This is a portable suitcase, you may try to move it in place or adjust the kickstands angels to get better sunshine. The ideal output of it will be around 500 Watt-hours per day (Calculated based on 100Wx5h expected sunlight availability).

The 12V/24V in product titles (ex. 100W 12V Monocrystalline Solar panel) does not refer to the actual voltage (Voc or Vmp) of the solar panels, but rather to the voltage of the solar system or energy storage system to which the panel is best suited. The voltage of the solar panel must be higher than the solar system voltage.
