The first one didn't work but I was sent a replacement right away and it went perfectly. No problems at all. Review: Solar Charge Controller Works Great - This 100a version works great and you must do your research before buying any of these items to prevent premature failure and possible fires. I consult for remote solar powered systems on a budget. One thing to note is writing down how many amps you need from this controller as it will output 12V or 24V depending on your setup. I recommend 24VDC battery setups on this, 24VDC inverters, and it will then need solar panels that supply 24V+ to this controller. Its good to read all the instruction booklets for parts to see what its hookup requirements are and its min/max settings needed. ## Features - Advanced Maximum Power Point Tracking (MPPT) technology, with efficiency no less than 99.5%.
