High efficiency 80A MPPT solar charge controller for solar panels up to 1000W (12V) / 2000W (24V) / 3000W (36V) / 4000W (48V) up to 200V

MPPT Technology: This solar charge controller utilizes the latest Maximum Power Point Tracking (MPPT) technology to optimize the power voltage point of solar panels as it changes with sunlight exposure and temperature. This technology guarantees maximum efficiency for your solar system and performs better than standard PWM solar controllers.

The MPPT technology also allows for a wide solar input voltage range, enabling the controller to work not only with standard off-grid 12/24V solar panels but also with multiple panels having a voltage of up to 200V. The maximum combined input solar power allowed for this controller is 1000W for a 12V battery system, 2000W for a 24V system, 3000W for a 36V system, and 4000W for a 48V system. This controller is particularly effective in increasing 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 possible efficiency for your solar system. These include preventing reverse current at night (from the battery back to the solar panel), automatic cut off to prevent over-charging and deep discharge, solar panel over voltage, and short circuit protection. The controller also incorporates an automatic over-temperature power reduction function which reduces the controller's power when the temperature increases. The controller's self-diagnostic capability highlights any system errors using advanced fault-targeting technology.

Advanced system monitoring: The controller automatically recognizes 12/24/36/48V battery systems (a battery should always be connected to the controller first before connecting a solar panel). The built-in LCD screen shows real-time charging parameters such as voltage, current, 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). The removable front panel provides access to a replaceable fuse in the terminals compartment. In addition, the controller features dry contact load terminals to switch the load output on and off, dry contacts for starting a generator when the battery is low, and a current limiting function (80A) that enables the possibility of adding more solar panels to the solar system in the future. Moreover, the controller has parallel connection capability, allowing it to connect to up to 5 additional identical controllers in parallel to expand the system using the parallel charging adapter (additional cables required).

Multiple connectivity options: This model incorporates 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 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). If using the RJ45 to USB cable, the user also has the option to create a user-defined battery type with charging parameters specific to their battery (if the pre-existing options are unsuitable).

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.

The controller has a built-in temperature sensor and intelligent heat-dissipating design. Additionally, it features a socket for connecting a remote temperature sensor to measure battery temperature more precisely and optimize the charging process.
