MPPT 30A Programmable Solar Charge Controller 12V / 24V / 36V / 48V

for AGM, Lithium Gel, Lead Acid, SiO2, Carbon Foam & Lithium Iron Phosphate batteries

This High-Quality MPPT Charge Controller features a clear display that shows the battery voltage and the Amps into your battery, which is your rate of recharge.

Will monitor your solar panels generating power and track the highest voltage and current values in real time to enable the system to charge the battery with maximum power. Used for off-grid photovoltaic systems to coordinate operation of the solar panels, battery and load, functioning as the core control unit.

Features an LCD screen that dynamically displays the operating status, operating parameters, controller logs, historical data, etc. Fully programmable.
MPPT that converts up to 150 Volts down to 12V or 24V or 36V or 48V and bumps that amperage way up. This controller works well with 60 and 72 cell panels.
Pre-programmed charging profiles, including Lithium, AGM, Gel, Flooded Lead Acid PLUS the ability to program all settings for non-standard batteries like Carbon Foam and Silicon Dioxide.
Has a temperature sensor, so it can automatically adjust settings based on the temperature.
There is a remote meter available as well, so you can look up and adjust all your settings from inside at your convenience.
