320W Solar Panel: This high-efficiency, waterproof 320W 12V monocrystalline solar panel is perfect for permanent outdoor use. It provides free electricity for charging 12V batteries to power various applications such as camper vans, motorhomes, boats, sheds, farms, as well as remote applications like telecommunications or monitoring equipment. It can also be used to provide a direct power supply for applications not sensitive to changes in input voltage or current, such as electric motors or pumps. The panel comes with 5m of special solar cable for high roof temperatures and minimum power losses. A pair of male/female MC4 connectors are crimped on the end of the cable for easy connection to other solar panels, your existing system, or a 6mm extension cable. (The MC4 connectors can also be cut off when wiring to the screw terminals of the solar charge controller.) The long-lasting, high-efficiency monocrystalline solar cells, and the tough, sealed aluminum frame will give you years and years of consistent, free power. The waterproof design ensures the panel can be used in all weather conditions.

This panel features innovative 5 busbar solar cells, which are more efficient than the 2, 3, or 4 busbar solar cells used in most other solar panels. These cells can extract more power from the same surface area, resulting in a smaller overall solar panel, making it ideal for applications where space is limited. They are also the best choice for applications in warmer climates, as they operate well even in high ambient temperatures.

Additionally, the kit includes a powerful 20A 12V/24V solar charge controller, designed to protect batteries while charging them. It has automatic cut-off to prevent over-charging and deep discharge. The controller uses PWM (Pulse Width Modulation) technology, which increases charge acceptance and prolongs the life of the battery. It can recover some lost battery capacity and stops reverse current at night (from the battery back to the solar panel) to prevent the battery from losing any charge. The controller also has other protection functions such as overcharge/discharge, overload, short circuit, overheating, etc. Other features include LED indicators, a temperature sensor, and a load "on/off" button.

Sure, I can help you with that! Here's the information you wanted me to remember:

One of the great advantages of this powerful 20A solar charge controller is its small size - only 16 x 8cm. The controller can work with sealed, gel, and flooded batteries (the default is sealed), or a user-defined battery type. Please note that the battery type can only be changed from default using one of the communication methods listed below. The solar charge controller features advanced communication technology, which allows the user to monitor and program parameters through various methods:

1) The controller can be connected to a remote meter MT50 with an LCD screen to display system performance information. This allows the user to manually adjust parameters and load settings.

2) The controller can be connected to a Wi-Fi module to create a Wi-Fi network, which enables your mobile phone or tablet to monitor or adjust charging parameters and controller settings through a free mobile app called Solar Station Monitor (available for Android and iOS users).

3) An RJ45 to USB cable can be used to connect the controller directly to your PC or laptop, where parameters and settings can be monitored and adjusted via a free computer program called Solar Station Monitor (only compatible with Windows-based PCs and laptops).

By using one of these communication methods, the user will gain access to various charging parameters such as voltage, current (separately for solar panel/load), battery state of charge, accumulated charge and discharge energy, min/max voltage, and other information. The user will also be able to amend the battery type and capacity, set charging volts for different charging stages, specify the duration of each charging stage, create a user-defined battery type with specific charging parameters, personalize the 'load' settings, and more.

In addition to the built-in temperature sensor, the controller has a pair of terminals for connecting a remote temperature sensor, which can be attached directly to the battery to measure the battery temperature more precisely and optimize the charging process.

Please note: This is an essentials kit and does not include mounting accessories or battery cable. If you require these additional items, please purchase them separately.
