Off-Grid Energy Storage Systems
AEGIS LiFePO4 battery systems for off-grid communities, rural electrification, telecom towers, and remote facilities — reliable power without grid dependency.
Energy Independence for Communities Beyond the Grid
Over 600 million people in Sub-Saharan Africa lack access to reliable electricity. Off-grid solar + storage systems are the fastest, most cost-effective path to electrification — bypassing decades of grid infrastructure development.
AEGIS off-grid battery systems are engineered for the specific challenges of remote deployment: extreme temperatures, limited maintenance access, and the need for absolute reliability.
The Challenge
Off-grid installations face unique demands:
- No grid backup — the battery system is the sole power source during non-solar hours
- Harsh environments — dust, heat, humidity, and temperature swings
- Limited maintenance — technicians may be hours or days away
- Deep cycling — daily charge/discharge cycles at high depth of discharge
- Cost sensitivity — projects must demonstrate clear ROI for funding
Our Solution
AEGIS off-grid battery systems provide:
- Complete energy autonomy — solar panels charge the batteries during the day, batteries power the load at night
- Deep cycle capability — LiFePO4 chemistry handles daily 80–90% DOD without significant degradation
- Wide temperature range — reliable operation from -20°C to 60°C
- 10+ year lifespan — 6000~8000 cycles means fewer replacements and lower lifecycle costs
- Minimal maintenance — sealed design with smart BMS handles all protection functions automatically
Product Options for Off-Grid
Residential Off-Grid
For individual homes and small facilities:
| Model | Capacity | Best For |
|---|---|---|
| AEGIS RES-5K | 5kWh | Basic lighting, phone charging, small appliances |
| AEGIS RES-10K | 10kWh | Full household — lights, fridge, TV, fans |
| AEGIS HOME-15K | 15kWh | Large household or small commercial |
Community & Mini-Grid
For schools, clinics, community centers, and mini-grid applications:
- Multiple AEGIS residential units in parallel
- AEGIS CI-241 for larger community power systems
- Custom configurations available for specific project requirements
Telecom & Infrastructure
For base stations, repeaters, and remote monitoring equipment:
- 48V systems compatible with standard telecom rectifiers
- Rack-mount and cabinet options
- Remote monitoring via RS485/CAN for unmanned sites
Why LiFePO4 for Off-Grid
Compared to traditional lead-acid batteries commonly used in off-grid systems:
| Feature | AEGIS LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle life | 6000~8000 cycles | 300–500 cycles |
| Usable capacity | 80–90% DOD | 50% DOD |
| Weight | 3–4x lighter | Heavy |
| Maintenance | Zero | Regular water topping, equalization |
| Lifespan | 10–15 years | 2–3 years |
| Total cost of ownership | Lower | Higher (frequent replacements) |
A single AEGIS LiFePO4 system replaces 4–6 lead-acid battery banks over a 10-year period, dramatically reducing lifecycle costs and waste.
