High efficiency 10A MPPT solar charge controller with built in Bluetooth for solar panels up to 130W (12V) / 260W (24V) up to 100V

MPPT Technology:

This solar charge controller uses the most advanced Maximum Power Point Tracking (MPPT) technology to track the maximum power voltage point of solar panels as it varies depending on sunlight exposure and temperature. This technology ensures the maximum efficiency of your solar system and significantly outperforms standard PWM solar controllers. Another benefit of MPPT technology is the wide solar input voltage range - this controller can work not only with standard off-grid 12/24V solar panels, but also with multiple panels with voltage up to 100V. The maximum combined input solar power allowed for this controller is 130W for a 12V battery system or 260W for a 24V system. In particular, this controller will significantly increase efficiency of a solar system where the solar panel voltage is much higher than the battery voltage (e.g. charging a 12V battery with a 36V solar panel).

Full system protection:

This charge controller features a comprehensive set of electronic protection functions to ensure the maximum possible efficiency of your solar system. These include: reverse current prevention at night (from the battery back to the solar panel), automatic cut off to prevent over-charging and deep discharge, solar panel over voltage, over load, short circuit and reverse polarity protection.  The controller also has self-diagnostic capability and highlights any system errors using advanced fault-targeting technology. 

Lithium Battery charging:

This solar charge controller is designed for compatibility with lithium batteries. It offers a lithium battery charging mode, which can be easily selected via the LCD display, mobile app, or PC software (refer to the user manual for details). Additionally, a "User-Defined" battery type option allows you to customize charging parameters for specific battery types.

Advanced system monitoring:

Built-in Bluetooth connectivity allows for parameters to be monitored and changed via the mobile app.
The controller automatically recognises 12/24V battery systems (note a battery should always be connected to the controller first before connecting a solar panel).
Built-in LCD screen shows real-time charging parameters such as voltage, current (separately for solar panel / load), battery state of charge, and historical data for accumulated charge and discharge energy.
Easy to use buttons allow the user to manually select the battery type (sealed, flooded, gel, or LiFePO4) and program load settings (e.g. set timers for lighting, fans, pumps etc).
 

Multiple connectivity options:

This model also features additional 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 MT52 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 (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 not only to the standard charging parameters already shown via the built-in LCD screen, but also additional information such as min/max voltages, temperature, protection cut off voltages, diagnostics and other information. If required the user will also be able to amend the battery 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), and more.

In addition to the built-in temperature sensor and intelligent heat-dissipating design of this controller, there is also a socket 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. (Inbuilt temperature sensor is not enabled for lithium batteries).
