Hello everyone, I’m excited to share my recent experience with integrating the Shelly Pro 3EM and BKW system to enhance my home’s energy management. As someone who values sustainability and efficiency, I’ve been exploring ways to optimize my solar energy usage and reduce reliance on the grid.
I recently set up a BKW system comprising the Shelly Pro 3EM, a Shelly PM Mini Gen. 3, four 450Wp solar panels, and a Marstek Jupiter-C storage unit. The goal was to achieve near-zero net energy consumption. While the system performs well, especially on sunny days, I noticed some inefficiencies. For instance, excess solar energy is often fed back into the grid, and occasionally, individual solar modules are disconnected when the storage is full, which feels like wasted potential.
To address this, I considered adding a second Marstek Jupiter-C unit and distributing the solar modules across different phases. This setup would allow for simultaneous power distribution, bringing me closer to my zero-energy target. However, I’m unsure if the Shelly Pro 3EM can support two Marstek Jupiter-C units on separate phases simultaneously. The app allows adding multiple storage units, but I need confirmation on the technical feasibility.
I’m also exploring the possibility of disabling grid feed-in to avoid exceeding the 800W limit, which would prevent any issues with the energy provider. If anyone has experience with similar setups or insights into optimizing energy distribution with multiple storage units, I’d greatly appreciate your input.
This project has been a fascinating journey, and I’m eager to refine it further. Thanks in advance for your advice and support!
