My SQ 3-2 pump has operated well for ten years, operating on a CU 200 control unit. It continued to work fine on solar (500 W) or 120V AC generator.. I have replaced it with a new pump (SQ 6-2) because I need more water. The old one worked fine and I am saving it for a spare. The new pump has only a F3 fault reading on the CU 200, both on solar and with the 120 V generator. Any ideas on what to do next would be appreciated.0 ·October 15

Further description. This SQ 3-2 pump has worked at this site for ten years operating on a CU 200 control unit . It continues to work fine on solar (500 W) or 120V AC generator. I have replaced it with a new pump (SQ 6-2) because I need more water. The old one worked fine and I'm saving it for a spare. The new pump records an F3 fault reading on the CU 200, both on solar or with 120V AC generator. Any ideas on what to do next would be appreciated.0 ·October 14

Can anyone tell me how deep to place my solar pole 13 ft long aluminum pipe with 8 inch diameter and 1/4 inch thick with attached rack of 2 inch 1/4 thick railng and 6 lg 300 watt solar panels mounted at top with 30 degree angle. Wind speed max of 120 mph wind load for over kill for my Maine camp. Also how much Cement in hole? Sheila0 ·October 9

Ryan, what happened with your turbine? I have a whisper 500 with the exact same symptoms. Bought it used and have never been able to get it going.0 ·October 5 -

Ohwinniepooh,
Welcome to the forums.
I suggest you start your own discussion (thread) in one of the main forums (beginner, RV, or whatever is closest to your needs).
And, I would also suggest you tell us a bit more about yourself... Your loads (watts and watt*hours, Amps and Amp*Hours at xx volts, etc.), your needs (summer/weekend RV or Cabin, full time off grid, emergency backup, etc.). Where the system will be installed/operated (fixed in sunny region, RV, fixed in great white north, etc.).
And the reason you would like MPPT vs PWM type controller. MPPT tend to be more expensive, have more options, and even Internet capability for some. PWM are cheaper, and do work just fine for smaller installations... (starting suggestion, 400 Watts or less, PWM; 800 Watts or more typically MPPT). Also if the panels are close to the battery bank/charge controller--PWM works fine. If you have a long(er) distance from battery bank to the array--Then MPPT controllers allow you to run a "higher voltage"/lower current solar array (long distance wiring with smaller diameter/less costly copper cables).
Many times, a "cheap MPPT" controller does not work as well as a good quality PWM controller. And many really cheap "MPPT controllers" from EBay and such, are really just PWM controllers with "MPPT" in the name.
Take care,

Admire your expertise and looking for advice.
Trying to find 2 sunpower X21-470-COM or E20-435-COM (whatever I can get a hold of)
Goal is to get the lowest cost MPPT that will charge a 24v AGM gel bank. And a suggested model MPPT if possible.0 ·September 30 -
