I’m typing a LOT!!!
But I don’t like people to “interpret” meanings on what is not said i.e. “reading between the lines”.
And it helps a LOT thinking “aloud” in a “group”.
It was the idea initially yes … and then it evolved cause as I “walked the talk” I realized… this is not for everyone to organize, and the “fat lady has not sung yet” (cells still to arrive) … which lead to the question: How can one mitigate the risks overall yet keep the price per cell low enough that more referrals come in from happy buyers AND I don’t mind doing it on a regular basis, which in turn further ensures the 3-year warranty?
What put me off initially was the massive costs, till we got that sorted i.e. upfront payments, which stems from the fact that I realized that I cannot buy anything from anywhere unless I pay first. So “pass it” on was put in place, cutting out a lot of “padding” in the per-cell price. Cause if I borrowed half a bar to import enough cells to sell and honor the 3-year warranty, R3500 per cell would have probably been the lower number per cell …
But that then made a battery bank cost like R66 000 incl BMS, most DIY’ers then going for 100ah cells … till they want to upgrade, adding another bank and yet another to get to 280ah cell levels to ah.
Brandnames cost a ton for a 15kWh range bank, and it involves a lot of wiring and parts.
Another idea was also born … me with my existing 150ah bank where I’m going to replace 6 cells with 280ah cells, is another component for DIY’ers in that as I replace 6 of my 150ah cells, the next “starter upper” goes from 100ah to 150ah cells piecemeal, or 280ah ones … new opportunities methinks. Along the lines of “got yourself in a bit of a corner, no sweat, sell it on” aka along the lines of “passing it on”.
Furthermore, if one focuses on just one type of cell, learning all about them and their performance over time, and one brand of BMS, that is mos “brand” building = DIY’ers go-to supplier?
The ONE thing I don’t want to get involved in like Plonkster always alludes to is direct support for wanna-be DIY’ers. Helping a knowledgeable person is one thing, having to spend hours finding a problem for no “reward”, unless it is learning, is costly. Costs a ton of money to keep a trained “support desk” in place.
Therein my “DIY market only” focus with forums like this the “community” support … or via value-adding-resellers.
For methinks, once we have ALL the settings down to a T, the volts, the cells, the BMS programming, this COULD be a DIY’ers nirvana!
