Curtech 12V Water Resistant LCD Solar Controller / Regulator
$78.00 – $104.00
10Amp or 20Amp Options Available.
This Curtech Solar Controller has some new features which will not only help maintain your battery charge but will also provide you with information so you are in control.
One of the features is the ability not to only show a battery voltage but this regulator will display 100% in the bar graph at the top of the screen when the battery is fully charged. It takes the guess work out of knowing if your battery is charged or not.
In addition to this, by a simple press of the voltage button the Amps which are being input to your battery will display.
By pressing this button again the accumulated Amps output to your battery will be displayed.
This Curtech Regulator will not only charge the standard AGM, Gel and Flood batteries it can also charge LiFePO4, LTO (Lithium Titanium Oxide) and Calcium Batteries.

GOOD PRODUCT AND SERVICE AS USUAL

Easy to install. Connectors aren’t up to the task so I ended up using my own. Runs my fridge and still puts charge into the battery on a dreary Ballarat winter’s day with rain.
