Well Engineered Backup Power Jun 01, 2011
By G. R. Baxter
I purchased this Humless Sentinel as backup power for power outages and for the eventual major earthquake in the Palm Springs Area (I hope this one doesn't happen). What interested me was the long life lithium based battery and all the controls in one box. I had made a lead acid based battery system years before and have also read many reviews about the negative aspects of using "car/RV batteries". I wanted a clean system that would hold a charge for a very long time and really be ready when the need arises. It's a 50 amp hour system so it is not designed to make up for the loss of power to major appliances, but it runs lap top computers, small TVs, LED/CFL lighting, fans and basic necessities quite well (up to 1000 watts continuous).
This product, although pricey, is well built and performs as described. I also purchased two 90 watt solar panels and some cabling from Humless directly (from their web site at Humless.com), that allow the system to recharge during longer power outages. The panels fully charge the Sentinel in about 4 hours, and are plug and play - meaning the twist-on connectors hooked up in seconds without any hassles at all. This means I can use the device during the day and still have some power for the evening hours. I still have the portability and it stores in a small closet space with the solar cables running up to my roof.
The Humless team in Utah was very helpful answering questions during a few telephone calls to verify that coupling the Sentinel to their solar panels along with my "install skills" would get the job successfully done. I'm happy with the purchase and results.
