At long last, I'm migrating my panels to the roof of my off-grid cabin. A new exposed-fastener metal roof was put on last fall. I'd like to do this mostly myself, with some help from someone who will probably know less than me. Fortunately my roof access is conveniently low so not a lot of...

I'm told by Outback that my MX60 is not compatible with lithium. Not that it might not be time to retire the old girl, but... The situation I have now is that I've put into play Kilovault 2400 HLX+ batteries with this controller (for the moment anyway) and have put aside my set of...

Each year, I shut down my off-grid vacation cabin on Canada's Prince Edward Island for the winter. Over the years, with my flooded lead acid Rolls S-460 batteries, I would leave my charge controller on and three of my six 245-watt panels on. This would extend about six months until I arrive...

I'm in the process of buying two 12v 200 kwh LifePO4 batteries. My vendor states they must be charged after they arrive and have recommended this IOTA DLS-45 charger. It's a bit pricey for what seems like almost a one-time use, though I could use it as well for additional batteries as the need...

After years of a crude home-brew fixed panel mount setup I'm looking at installing something I can tilt. I found this reasonably priced Tamarack horizontal two-pole system for up to six modules. Product # UNI-PGRM/5P2 Anyone use this and can comment on it? Thx

After many years with a trusty Outback MX-60, I am seeing the need for an updated charge controller. My off-grid cabin is in a location with no professional solar support, and the only electrician versed in solar is so busy he doesn't return calls. My original installer (15 years ago) is...

My completely non-expert impression is that SimpliPhi is highly regarded, maybe considered the best of the bunch. I've also seen a lot of attention around Kilovault. What strikes me as curious, though, is the fact that Kilovault and alt-E, an RE distributor, have the same physical address...

I can swear it's getting harder to charge batteries by the sun these days. More overcast conditions, dusty, smoky atmosphere in my maritime Canada location? Whatever it is, after many years with my existing array in my off-grid situation I need to increase solar output, not that I had a ton...

Right now my array consists of five Solar World modules: Specification SW 235 Poly Peak Power Watts (PMAX) 235 W Maximum Power Voltage (VMPP) 30.0 V Maximum Power Point Current (IMPP) 7.85 A Open Circuit Voltage (VOC) 37.0 V Short Circuit Current (Isc) 8.35 A ...and one GMA Solar module...
