Zendure SolarFlow AB3000L Add-on Battery (3kWh Stackable LFP)

This LFP pack stores everything my panels produce during the day and runs my living room all evening. Stacking with my existing units was literally plug and play. Ten-year peace of mind on top of it.

You get a lot of storage here — a full 3kWh that integrates seamlessly with SolarFlow. Just measure your space first; it's a large unit. Performance has been flawless for two months.

Stacked two of these, zero issues. Excellent.

Capacity is exactly as rated and the app tracks it precisely. Nothing fancy, it just does its job quietly.

I added three of these AB3000L units to my SolarFlow system over six months and now my house barely touches the grid in summer. Each battery was recognized instantly, no configuration headaches. The LFP chemistry means I don't worry about cycle degradation like my old NMC power bank. The stacking design saves enormous floor space. Worth every penny, even at full price.

Keeps my freezer, router, and lights going through extended outages. The BMS reporting is detailed and reassuring. Slight fan hum during high charge rates but nothing annoying.

My off-grid cabin now runs a small fridge, water pump, and LED lighting comfortably. Even my grandson set up the app monitoring for me over the phone. Dependable storage is exactly what I needed.

No complaints about function — charges fast, integrates cleanly. At the regular price I'd have hesitated, but on sale it's a clear win.

Second battery in my stack arrived with a cracked corner. Replacement process was okay but it delayed my setup by a week. The working unit performs fine.

Before adding this battery my surplus solar was wasted after noon. Now every watt gets banked and used after dark. The throughput numbers in the app confirm thousands of watt-hours captured monthly. Genuinely changed how I think about my energy usage.
