BigwitEnergy:
We are also trying to develop a packed kit for rural areas to install off grid solar. We are having heavy discussions on about which technology to use as cost is a very important factor here. Some people might understand the cost of quality vs the price but we want to make it affordable for everyone.

Any one who can help and has a experience in launching this kind of product please help us.

No problem.

Probably, I used the enclosure, but different operating system, makeskyblue uses unknown chip and smaller inductors, while I used pic micro chip with bigger inductor .

my very first version, dual phase, maximum of 40a . Before modification to 3 phase now 75a maximum. Y'all would try out my product once it's ready for end user. I enabled only serial communication, equalization enabled for lead acid batteries.

You got it spot on It is Makeskyblue, branded in Nigeria

Probably, I used the enclosure, but different operating system, makeskyblue uses unknown chip and smaller inductors, while I used pic micro chip with bigger inductor .

Three signals for the three Buck converters for higher efficiency.

We recently designed our mppt solar charge controller, targeting Nigerian market, our mppt comes with two year warranty, affordable and reliable, 98% efficiency, utilizing three phase Buck converters for higher current and higher efficiency.

Preparing our mppt for Nigerian market.

we now have our three phase signals, our updated mppt is featuring 3phase interleaved mppt, 98% efficiency. limited to 60a, input raised to 300vdc, output up to 96v . Ghost power technologies .

Our MPPT is featuring this packaging, and will soon be available for purchase in Nigerian market ��. moved from pic16f876a to more powerful processor for better performance. designed by Ghost™ .
