Product Features:

1.12V/ 24 V system voltages are automatically recognized.
2.An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charging to the battery periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfuration, thus extending the battery's service life.
3.With temperature compensation employed, charging parameters can be automatically adjusted.
4.A wide range of load working modes facilitate the product's application to different types of load.
5.The product provides overcharge, over-discharge, overload protection, as well as short-circuit protection.
6.By virtue of an advanced load starting method, large-capacitance loads can be started smoothly.
7.The product provides a dot matrix graphic LCD screen and a human-machine interface with a key.
8.The user-friendly design of browser and dynamic interfaces ensure convenient and intuitive operations.
9.Boasting an industrial grade design, the product can function well in various tough conditions.
10.TVS lighting protection is adopted.

Hi people,
I think purchasing the
SRNE (ML2440) 40 Amp MPPT Charge Controller was a good choice as it has been in use for a few weeks and is doing a good job. I charge with 300 watts of 18v PV and have two deep cycle 12v batteries. When the output voltage got run down the automatic shutoff feature worked well and I spent a little time figuring out how to reset it once the batteries recharged. So far so good!

The charge controller was functional right out of the box and well designed for easy installation. Great. Readouts of voltage and amps so no I. A monitor the functioning of my panel. Delivery to my remote, off grid location was.worry free.

Works as advertised. Not CSA, so knockouts don't take standard connectors. Overall good value for the price for a small PV system.
