Article Summaries:

  • EEVblog episode 1719 documents a major upgrade to the AERL home‑storage system. The 25 kWh battery rack is expanded to 75 kWh using AERL’s 10‑way outdoor cabinets, and the 5 kW Deye hybrid inverter is replaced with an 8 kW Solis S6‑EH1P8K‑L‑PLUS hybrid inverter. A new changeover switch and 10 sq mm cable run allow most of the house to be powered from the inverter’s backup port. The video covers cable sizing, crimping, PVC routing, switchboard upgrades, and stress‑testing of the Solis backup port, concluding with initial troubleshooting and a first‑time test.
