Product Description

These high performance 20 Watt & 50 Watt solar charge controllers increases battery life by preventing overcharging. Overcharging can cause corrosion and buckling of the lead plates, increased battery water loss and excess hydrogen gas.

The control also prevents power loss back into the solar module at night, so an external blocking diode is not required (most rollable & foldable solar panels include a blocking diode, but many rigid panels do not).

Unique no battery drain – Battery standby power consumption is zero! In the dark they use absolutely zero power, ideal for PV systems where efficiency is important. Other controls, which have a standby current draw, will drain the battery over the winter with no solar input, reducing the freeze protection of the battery.

Eco Energy’s latest innovation; automatic nighttime shutdown with an intelligent design results in the controller using < 1/10th the power of the industry average. Other controls stay on all night, wasting precious power. Save up to 10% of the power from a 5 Watt module.

Safer – Eco Energy controllers have more built in protection and safety features than any others on the market. They feature automatic over-temperature shutdown, protection from battery removal conditions, over-current, solar and battery reverse polarity, short circuit and over-voltage protection of the inputs and outputs. Eco Energy is the first to combine all of these safety features into one controller. In remote applications, there is no need to worry about accidentally damaging the controllers.

Going solar with confidence has never been easier.

The new
ASC charge controllers provide you with many benefits over the Sunguard.
