Re: [RE-wrenches] Combining Enphase M190 and M215 on same circuit
Jason, The M190 requires using a 15-amp (maximum) branch circuit. As long as the total current from both types of inverters doesn't exceed 12 amps (80% of 15), there should not be a problem in mixing the inverters. The combination you are proposing is only 8.6 amps -- it should be fine.

Re: [RE-wrenches] Combining Enphase M190 and M215 on same circuit
Hi Jason, You can do that, but will need to maintain the 15A limit of the M190s. For a single-phase, 240V application, with 3 M190s (3*0.8A = 2.4A,) you can install up to 10 M215s.

Re: [RE-wrenches] Lorentz Pumps
We have 1 Lorentz installation in Haiti and about 9 in West Africa - pumping around 10,000 gpd. Started using them a few years ago because we were having lots of problems with Grundfos. To date, I believe we've had problems with 1 controller and 1 pump. (not sure, but a wiring error on the part of our local techs might have caused one of these problems) We're now buying from American West Windmill and Solar in TX (800530-4744) and have had good service from them. For our next round of systems, we'll probably be looking at Sunpumps as well.

Re: [RE-wrenches] Lorentz Pumps
Interesting about the licensed pump installer, because in New Mexico there is not a license. I've been installing PV pumping systems since 1988, so I tire easily now when companies won't work with me, because I'm not qualified. I actually installed some of the Mono hand crank and electric powered pumps in Morocco before it was ETA or Lorentz. I'll talk to Genpro on Monday.

Unfortunately, as I understand it, Lorentz will not sell to anyone that is not a licensed pump installer. You may talk to GenPro at http://www.genproenergy.com/lorentz-submersible-pumps.html to get the latest about Lorentz, or maybe team up with a licensed pump installer and do the solar part. We have had great results with the Grundfos SQFlex system for anything that we have installed and haven't found the need to specify a Lorentz.
