Excludes DG or bulk items (flooded or large lead acid batteries, large panels and generators).

Finally a consumer grade MPPT solar charge controller that is compatible with traditional Lead Acid batteries as well as modern LiFePO4 batteries!

Adopting Maximum Point Tracking (MPPT) for maximum efficiency and best use of available power. This model is suitable for 12v, 24v, 36v or 48v lead acid batteries (AGM, Gel and Flooded) as well as (only) 12v LiFePO4 batteries.

This model can scale up to 12v 700w or 24v 1500w. We recommend batteries with a capacity of 50ahr or more.

This unit features three timer programs, three charging stages and an LCD status display that shows real time condition of battery, load voltage, PV voltage, time and much more. The package includes an external temperature probe that will adjust float voltage for lead acid batteries depending on ambient temperature.

The integrated Wi-Fi enables you to remotely access the controller using an app on your Smartphone to keep an eye on the system, and two USB ports are provided to charge your USB gadgets. The fan less design is built into a durable case for permanent installation with heavy-duty screw terminals for cabling up to 6AWG. Over-voltage, low-voltage protection, reverse connection, short-circuit, over-current, and over-temperature protection included.
