We’re adding 1 more neighbor. It would disrupt our inverter KVA calculations, but we already implemented a human-in-the-loop system and are working on an AI control system for efficient inverter management. Site 4 still has about 60% oversupply every day, based on remaining battery levels from dusk to dawn.

We’ve added dedicated operator dashboards to Sites 3 and 4 of T&S Power Grid—bringing more human oversight into how we manage shared electricity. Here’s what prompted the build. Site 4 serves 16 single-phase households from a 12kVA inverter and a 30kWh battery. We allocated a maximum of 0.55kW per household, with a higher allowance of 1.5kW each for three households using air conditioners. That creates a potential simultaneous demand of: 13 × 0.55kW + 3 × 1.5kW = 11.65kW Our highest observed inverter draw so far has been around 6kW. But the highest load we’ve seen is different from the highest load our allocations could allow. As usage patterns change, more households could draw heavily at the same time. There’s an important distinction here: kVA, kW and kWh describe different things. •kVA is apparent power. A 12kVA inverter’s continuous kW rating must be checked separately; we shouldn’t assume it can continuously deliver 12kW. •kW is the actual power being drawn at a particular moment. •kWh describes stored energy. A 30kWh battery helps determine how long we can supply a load; it doesn’t, by itself, establish how much power the system can safely deliver at once. Air-conditioning equipment can also introduce startup demand, depending on the compressor and its controls. That makes operating headroom worth paying attention to. So we built separate, view-only monitoring access for the operators of Sites 3 and 4. Each operator can see their own site’s neighbours and available load readings, identify rising demand, and coordinate usage when necessary. Human oversight complements the system’s electrical protections. It gives us another way to notice problems early and make informed operational decisions. For us, building shared energy infrastructure means thinking beyond getting electricity into homes. It also means protecting the equipment, managing simultaneous demand, and keeping that electricity reliable as more people depend on it. That’s the thinking behind this build: better visibility, clearer responsibility, and humans in the loop.

And in less than 5 days we are approaching 100k of energy sold to 16 neighbors.

I remember paying 100k+ early this year to the utility. Now in 4 months I’ve made 100k+ selling electricity to my neighbors at 200naira per KWH.
