Product Description

MPPT 20A Programmable Solar Charge Controller 12/24V ML2420

for AGM, Gel Lithium, SiO2, Carbon Foam and Flooded 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.
MPPT that converts up to 100 Volts down to 12V or 24V and bumps that amperage way up. This controller works well with 60 and 72 cell panels up to 260W at 12V and 520W at 24V.
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.
