In todays modern world there are many energy sources and storage methods available. The most design and powerful storage technologies are very expensive and controlled by patents. While there are many options for battery packs available there are not many open source solutions that have the same level of performance as the leading commercial solutions. SolPak is an attempt to build a open source battery pack that competes with the technology inside Tesla battery packs both home and car. There are many DIY powerwall and home battery storage projects online but SolPak will be using a custom BMS systemed based on the Tesla Model 3 battery pack.
SolPak addresses the energy harvesting problem from the storage side of things. There are many ways to generate electrical power, such as wind, solar, combustion, nuclear, and tidal. SolPak is none of those things though SolPak could hold the power generate by any one of them but I am choosing to focus on solar and mains voltage. Solar panels have come down in cost and have become more accessible, there are even ways to make DIY low cost panels, they also work off the grid in remote locations. Mains voltage is something available to most individuals on powergrids with homes, its always on and always available.
My focus with SolPak is to harvest energy from these sources for emergency use or remote use, a lot like the Tesla powerwall only free as in freedom. SolPaks can be deployed in the home to harvest AC power to keep the pack fully charged at all times until it is needed, either to power the home or something where mains voltage cant be found. The SolPak in solar applications will connect to a solar array to charge the pack. The pack will have a basic MPPT charge controller integrated into it but external panels will need to be bused together. This will allow users to use the pack with various solar arrays in different locations with easy and minimal external hardware.
Stay tuned and Lets Go!!!!
