<html><head><meta http-equiv="Content-Type" content="text/html charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Drake,<div class="">I\u2019ve run into this problem numerous times in the last year, as I\u2019ve had a number of off-grid customers that I have upgraded from legacy 12V or 24V systems to 48V. Left behind are often things like expensive DC fridges and DC heating pumps. I\u2019ve searched for converters a number of places and have found that eBay (and Amazon) have a ton of DC-DC converters available. Yes they are Chinese, and the many different brands seem to be clones of one another, so It\u2019s hard to pick one with confidence. I was suspicious of them at first, but have several out in the field that have worked well for some time now. Most are in the 10-20A output current range, but there are bunch of different voltage configurations available. Just do a search on eBay with your desired voltages and you\u2019ll pull something up. For the 48-12V conversion range, the solution I\u2019ve settled on is golf cart DC-DC converters, which tend to be high quality and are designed to run 12V lights and accessories from 48V golf cart battery banks. I find these on eBay as well and have had great luck with them.</div><div class=""><br class=""></div><div class="">-Luke</div><div class=""><br class=""></div><div class=""><br class=""><div class="">

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. <br class=""><br class="">
I need to step down power from a 48 V battery bank to power El Sid pumps
for an offgrid <font size="2" class="">hydronic</font> heating system.
