What products are the DIY solar manufacturers missing, and what would they make a killing on if they built it? Eric walked in blind to the topic, so every idea is worked out live, with the chat pile of AAA answers folded in. We cover the centralized communications hub every DIYer wants (the Victron Cerbo model that nobody else copies), the USB dongle grind, a brand agnostic monitoring hub and why it also solves the FCC remote access question, the universal battery communication hub and the battery to battery BMS Tower of Babel (JBD, Pace, Seplos, Pylon), Meshtastick and MeshCore control of inverters with no Wi-Fi, and the two GitHub projects that already exist for it. Plus Eric's watertight solar pergola roof and panel gasket ideas, the solar company that ships your whole kit with wiring diagrams and permit paperwork, the smart breaker and CT per circuit ideas, the inverter that auto starts a generator and the water heater timer trick for Chargeverter loads, alternator charging for 48 volt banks, a dedicated cell level battery screen that pairs like the Blue Eddy fridge power display, PoE powered monitoring per breaker, a customizable MPPT, a 120 volt smart outlet built into the side of the inverter, EcoFlow's Wi-Fi reconnection flaw, EV to MPPT high voltage handshake ideas, and the sunshine report with production totals from around the country.
