Or better yet, put your survey *here in your post on this forum*, where we can answer directly in our posts to you. (then those of us like me that can't access your survey could also help you)
If you are going to be like all the others that come here for answers and not bother to post the results back here, there's no reason for anyone to bother filling out your survey, as it adds nothing to the knowledgebase here on ES or the world, and just disappears down a hole.
Yeah, I contacted Midnite Solar asking if they could customize a charge controller for me. They won't.madin88 wrote:teslanv,
a normal DCDC converter wont work well for solar charging. what you like to use is a MPPT battery charge controller.
MPPT means maximum power point tracking which is really important for good efficiency (the power of the panel changes all the time)
I'm also searching for a solar charging system for a 16s battery. the problem is there seem to be not many options out there for such high voltage.
most controllers are for 12 or 24v, and the cheap boards from china are crap..
Genasun makes excellent controllers, but they told me the highest available CV voltage they offer is 62V which is unfortunately too less for 16s.
any suggestions welcome
Must take an awfully long time to analyze. Nearly half a year later, and no results posted here on ES yet, despite the above claim.mikepool96 wrote:No problem! After the results have been concluded and analysed, we will post them here.
Some Midnite and Morningstar charge controllers can be programmed to work with modern lithium batteries, you just need to download the free firmware and reprogram once you purchase. Or have your retailer do it, but many probably won't want to/want to mess with figuring it out. FYI it voids the warrantee. And you won't be able to boost the voltage, only reduce, so the Genasun is still the way to go if you have a tiny array. If you have enough panels to string to 48v, for instance, then you could use, like, a morningstar tristar to do it, or you could make 24v strings and run a 24v RC-style system. The marine version of the Kid by Midnite strikes me as a nice MPPT charge controller for something larger, like a solar tandem or actual car/trike thing. It is another CC that you can program to charge lithium batteries.
