Relevant charging information is stated on ABR, Morningstar & Steca websites!
ABR (Steca & SK-12 comparison)Morningstar SK-12 tech specsSteca tech specs
SK-12 regulator:
*Float Voltage - 13.7 Volts
*Regulation Voltage - 14.1 Volts
Type of Charging Series PWM 3 stage: being bulk, PWM and float.
Umm,
that looks like only 2 stage regulator to me
PWM does NOT put any charge into the battery, just advertorial blurb or bulsh1t
Remember this regulator is attached to the '
junction box' (as in picture) under the Solar panel, it "regulates" the Amperage there at the solar panel, and forwards it to the battery, this gives further loss at the battery, causing further charging inefficiency.
STECA regulator:
*FLOAT Voltage - 13.8 Volt
*BOOST Charge Voltage - 14.4 Volt
*EQUALIZATION Voltage - 14.7 Volt
Genuine 3 stage charging, and it can be clearly seen the Voltages available are much higher with the Steca regulator and being Voltage adjustable it's suitable for both wetcell & Gel batteries.
A
well engineered piece of equipment, used by BP Solar as their premier regulator.
