we always ensure that our products are of the highest quality. This is why we have selected premium German solar cells for use in this solar panel. These high-efficiency solar cells perform exceptionally well in low light conditions (particularly when compared to solar cells of other origin) and they produce a good amount of power simply in daylight, even when direct sunlight is not available.
250W solar panel:
This high efficiency, waterproof 250W 12V monocrystalline solar panel is perfect for permanent outdoor use to provide free electricity for charging 12V batteries to power various applications such as in a camper van, motorhome, boat, shed, farm, as well as remote applications such as telecommunications or monitoring equipment. It can also be used to provide a direct power supply for applications not sensitive to changes in input voltage / current (e.g. electric motors or pumps).
The panel is fitted with 5m of special solar cable which can work at high roof temperatures, with minimum power losses. A pair of male / female MC4 connectors are crimped on the end of cable for easy connection to to other solar panels, your existing system or 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 German solar cells and the tough, sealed, aluminium 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 also 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, and are able to extract more power from the same surface area. This results in a smaller overall solar panel, which is ideal for applications where space is limited. These solar cells are also the best choice for applications in warmer climates, as they operate well even in high ambient temperatures.
20A Solar charge controller:
This kit includes a powerful 20A 12V/24V solar charge controller, which is designed to protect batteries whilst charging them, with 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 your battery. Often PWM technology can recover some lost battery capacity.
This controller stops reverse current at night (from the battery back to the solar panel) so your battery won't lose any charge. It has many other protection functions such as over charge / discharge, over load, short circuit, overheating etc. Other features of this controller include LED indicators, temperature sensor, and a load "on/off" button. One of the greatest benefits of this powerful 20A controller is the small size - only 16 x 8cm.
This controller can work with sealed, gel, and flooded batteries (the default is sealed) or a user-defined battery type (please note battery type can only be changed from default using one of the communication methods listed below). The controller can handle up to 320W of solar power (12V system) or 640W of solar power (24V system), so the kit can be upgraded to increase the power output by adding more solar panels, without the need to buy a new controller.
The solar charge controller also features advanced communication technology, which offers the user the opportunity to monitor and program parameters for the solar charge controller through various methods:
1) The controller can be connected to a remote meter MT50 with an LCD screen, which displays system performance information, and 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, to which your mobile phone or tablet can connect, in order to monitor or adjust charging parameters and controller settings through a free mobile app - 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 / laptop, where parameters and settings can be monitored and adjusted via a free computer program - Solar Station Monitor (Windows-based PCs and laptops only).
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. If required 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 charging parameters specific to their battery (if the pre-existing options are unsuitable), personalise the 'load' settings (e.g. set timers for lighting, fans, pumps) 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 optimise 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.
