Features

MPPT technology

This solar charge controller uses advanced Maximum Power Point Tracking (MPPT) technology to track the maximum power voltage point of solar panels as it varies with sunlight and temperature. MPPT ensures maximum efficiency and significantly outperforms standard PWM solar controllers. Another benefit of MPPT 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 input voltage up to 100V. The maximum combined input solar power is 520W for a 12V battery system or 1040W for a 24V system. In particular, this controller will significantly increase the 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 maximum 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, overload, 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 compatible with lithium batteries when a lithium charging programme is selected using PC software (see below), and it allows charging parameters for lithium batteries to be set.

Advanced system monitoring

  • 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, accumulated charge and discharge energy.
  • Easy-to-use buttons allow the user to manually select the battery type (sealed, flooded or gel) and programme load settings (e.g., set timers for lighting, fans, pumps, etc.).
  • Current limiting function (40A) makes it possible to add more solar panels to your solar system in the future.

Multiple connectivity options

This model features advanced communication technology, offering several options to monitor and programme controller parameters:

  1. Connect to a remote meter MT50 with an LCD screen, which displays system performance information and allows manual adjustment of parameters and load settings.
  2. Connect to a Wi-Fi module to create a network for your phone or tablet in order to monitor or adjust charging parameters and controller settings through a free mobile app (Android and iOS), including setting charging parameters for lithium batteries.
  3. Use an RJ45 to USB cable to connect the controller directly to a PC / laptop and monitor or adjust settings via the free computer program – Solar Station Monitor (Windows only). With the RJ45 to USB cable, you can also create a user-defined battery type with charging parameters specific to your battery (if the pre-set options are unsuitable), including settings for lithium batteries.

Using any of these communication methods, you gain access not only to the standard parameters shown on the built-in LCD, but also additional information such as min/max voltages, temperature, protection cut-off voltages, diagnostics and more. If required, you can amend the battery capacity, set charging volts for different stages, specify the duration of each stage, create a user-defined battery type, and more.

In addition to the built-in temperature sensor and intelligent heat-dissipating design, there is also a socket for connecting a remote temperature sensor, which can be attached directly to the battery to measure temperature more precisely and optimise charging. (The built-in temperature sensor is not enabled for lithium batteries.)
