HI Harry, The battery is charged from the AC side correct? And is the charging algorithm inside the ABU. If so why couldn’t you use a generator to charge the battery? jay peltz power > On Sep 13, 2018, at 7:10 AM, Harry Mahon > wrote: > > Marco – > > The Sunny Boy Storage “Advanced

SCI was that Canadian company.  Samlex does make a 48 v to 24 v converter modelIDC-100C-24. However, I would consider skipping the El cid pumps and going to the new TACO or Grundfos ECM drive circulators. Ray Walters Remote Solar 303 505-8760 On 9/15/18 8:58 AM, Drake wrote: Since Solar

While not as inexpensive as David's solution, I have used Mean Well converters with success. This manufacturer supplied the DC-DC step-down converters used by Wattsun for their tracker drives, so there's a pretty long history with them. Check out

I have had great luck using cheap LED drivers. They say 110-240 vac input but they rectify the input to DC. I have used them to run 12 and 24 volt stuff off of 48 vdc and even 400 vdc. They operate down to about 35 volts dc. They are available in a variety of output voltage and current. And they

Since Solar Converters seems to have evaporated, I'm not sure where to look for a 48 to 24 V DC to DC converter. Samplex has 24 to 12. It seems like someone mentioned a Canadian company that makes these. I need to step down power from a 48 V battery bank to power El Sid pumps for an offgrid
