John, It's hard to imagine how the bolt could work it's way out with all that weight on it but obviously it did. I have ~40-50 DPW TPMs in the field (since late '90s) and have not had a failure of any kind other than snow and that was pretty easily repairable. I just finished

Dave, I just had my first ever failure of a DPW TPM-8 with 8 SolarWorld 260's on it. I installed it late last fall and the customer called last week to say that it is on the ground. It turned out that the nut on the main pivot bolt worked its way off, the bolt then worked its way out of on

Good answer Wayne…how strong AND how far away. I'm sure the inverse-square law apples here but if you don't know the initial power and distance, it does not matter much anyway. Now, for a hilarious interjection, there is a customer in our showroom at this moment asking about PV solar in case t

We get that question all the time. We reply with the same question that we ask them with regard to hurricanes. Well... how strong will it be? We have not found any good supported answer on line or otherwise. However, the answer I like the most is "You will either be completely fine or totally

Hi Karl, On their main page they claim charging "...with little or no electrolyte gassing." Gassing is a function of charge voltage. If you are charging deep cycle batteries properly, you will be gassing. After reading through the brochure, I'm not very impressed. Do yourself a favor and listen

Charge controller failure = system failure = customer sitting in the dark off grid. I would only use proven, UL listed equipment. Those are ridiculous current ratings. You would need to wire that with 500 MCM cable. If you look, you'll notice reputable brands like Midnite Solar, Outback, and B
