Originally, we started with a single EG4 indoor wall-mount battery, but quickly realized it wasn’t enough. Over time, we added a stack of AO Lithium batteries and an Eco-Worthy rack-mount battery—creating what I call our “Frankenstein” system. Now, we’ve expanded with another EG4 indoor wall-mount battery (what I call “Gen 1.5”) and I walk you through the subtle differences in design, firmware, and build quality between the versions. You’ll also see how everything is wired together using Anderson / Amphenol (Anderson SB / Degson) quick connectors, bus bars, and parallel connections to maximize performance. This video is perfect if you’re interested in: ✅ Off-grid solar and battery storage ✅ Victron inverter/charger setups ✅ EG4, AO Lithium, and Eco-Worthy battery comparisons ✅ Parallel wiring, connectors, and expansion tips ⚡ Whether you’re building your first battery bank or upgrading to handle bigger loads, this walkthrough shows real-world installation, wiring tips, and lessons learned.
