The Ideal Charge Controller for Home, RV & Marine Solar Systems.
The MARK/15 & MARK/20 (MARK/(15,20)) are highly reliable charge controllers that
are ideal for small to mid-sized photovoltaic systems. They will efficiently charge
your batteries and provide years of protection from over-charging. This protective
care will prolong your battery life and reduce maintenance requirements.
FEATURES
IDEAL SOLAR CHARGING
• Compatible – Works with almost all
types of batteries and solar panels
