The full 3-room scenario.
Real numbers from a real 3-room apartment. All appliances running simultaneously through load shedding.
What runs on the Home system
With every appliance listed running simultaneously. A full night of load shedding — covered.
1,000W solar recharges the 3kWh battery in 3–4 sunny hours. Even on a cloudy day, partial recharge keeps the system running through the following night.
The Home system is designed for continuous refrigerator operation. Nano is not.
A refrigerator draws 80–150W on average (compressor cycles). Running a fridge on the Nano is technically possible but significantly reduces runtime for your other appliances — leaving you with difficult choices during load shedding.
The Home system's 3kWh battery and 1.5kW inverter are sized specifically to handle refrigerator compressor startup surge (300–600W peak) without interruption — while keeping fans, lights, and everything else running.
Choosing the right system.
We will not push you to the Home system if the Nano is right for you. Here is the honest comparison.
| Situation | AAA Battery Nano ৳38,000–44,000 |
AAA Battery Home ৳1,15,000 |
|---|---|---|
| 1–2 rooms | ✓ Perfect fit | Overkill |

| Refrigerator backup | ✗ Not recommended | ✓ Designed for it |
| Full night coverage | 4–7 hrs (depends on load) | 4.5–5 hrs (full load) |
| WiFi monitoring app | — | ✓ Included |
| Net metering ready | — | ✓ Grid-tie capable |
| Warranty | 2 years | 5 years |
Sell power back to the grid.
The Home system is BERC net metering ready. During peak solar hours when your battery is full, excess power flows back to the national grid — and DESCO/DPDC credits your bill.
Net metering registration takes 6–12 weeks after installation. We manage the paperwork.
"Net metering ready (BERC approval per installation — 6–12 weeks)." This is not instant. We will tell you clearly what to expect.
How net metering works
WiFi Monitoring App
See real-time solar generation, battery percentage, power flow, and daily/monthly energy statistics from your phone. Know your system at a glance.
Cloudy Day Intelligence
The hybrid inverter automatically switches to grid charging when solar is insufficient — keeping your battery ready for the next load shedding event.
Always-On Priority
The Home system is designed with the fridge as a protected load. Even at low battery, refrigerator power is maintained above all else.
5-year warranty. Zero compromise.
The Home system comes with our longest warranty — because we built it to be the last backup system you ever buy.
