Renogy 400W Lightweight Portable Solar Suitcase

A solar panel has to be connected 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.

On-grid simply means solar power equipment (array or solar panel) is connected to the electrical grid, while off-grid refers to systems that are not connected to the grid and therefore store the generated power for later use. Off-grid systems are not affected by grid blackouts.

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.

Solar panels can be connected in series or in parallel to meet your electrical circuit size and power demand. Connecting solar panels in series will have the effect of adding up their operating voltage output, while system current output will be the same as that for one panel. While, connecting solar panels in parallel will have a different effect; individual panels operating current output will add up to be the system output current, while system output voltage will be the same as the output voltage of one solar panel. To meet the optimum power output and system rating for your power system, you can use both parallel and series connections.

The best way to gauge how many solar panels you need, is to understand and define the power load needed from this system. Power is measured in Watts, and capacity is commonly measured in Watt-hours (multiplying power output in watts by the required number of hours of operation multiplied by a safety factor of 1.5-2). Therefore, it is wise to size your battery bank first based on the minimum required capacity, and accordingly decide how many panels or how much power input is needed.

The 12V/24V in product titles (ex. 150W 12V CIGS 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.

This 400 watt solar panel is compatible with most portable power stations. Ensure the DC input voltage exceeds 48V. For optimal performance, pair it with a power station that has a high input capacity and an efficient BMS.

Ensure the controller matches your battery voltage and that the PV input voltage is within the controller's capacity. Upgrade if panel power exceeds controller capacity. The controller should support at least 30A for the 400W portable solar panel.

This 400W portable solar panel can be used with a charge controller to connect to your system battery or paired with a portable power station. To set up, you'll need adapter kit cables to connect the solar panel(s) and charge controller, and tray cables to link the charge controller to a deep-cycle battery.

Solar panels typically deliver about 85% of the rated power. It can exceed this in clear midday conditions but may drop in less ideal lighting or cloudy weather. To maximize output, set the panel in a shadow-free area and avoid prolonged shading.

This 400 watt solar panel is compatible with most portable power stations and is ideal for both solar power systems for home use and camper solar panel setups. Ensure the DC input voltage exceeds 48V. For optimal performance, pair it with a power station that has a high input capacity and an efficient BMS.
