 Testing Solar-charge controllers with LP batteries Sample 1: STECA SOLARIX MPPT 2010 This is a Maximum Power Point Tracking (MPPT) solar charge controller. It works perfectly. It gets the maximal power from the solar panel. The ideal peak reached was 200W of power input from 217Wp solar panel. The average solar input was 130W to 150W (from 217Wp panel during a sunny day in Prague, Czech). Sample 2: PHOCOS CIS20 This is a Pulse-width modulation (PWM) solar charge controller. This controller will limit solar panel output voltage according to the battery voltage. It is not suitable to be used with the high voltage FV panels (e.g. our 217Wp panel with max 36V). It is designed to be used with the so called “12V” solar panels. The ideal peak reached was 140W of power input from 217Wp solar panel. The average solar input was 80W to 90W (from 217Wp panel during a sunny day in Prague, Czech). You can download the test data results from the links bellow: http://www.auto88.cz/_info/Tests/STECA-SOLARIX-MPPT-2010-1.pdf http://www.auto88.cz/_info/Tests/PHOCOS-CIS20-1.pdf Concerning the LFP batteries The usage of the 12V LP (or LFP) batteries is completely trouble-free. Both regulators do not exceed 14V on the battery charge voltage output, so the 12V LP battery will never be overcharged. Be sure to contact us for more details on the use of the LP batteries with the solar controllers. | |
