Battery Options for Solar Energy Systems
Solar panels alone can only do half the job. To achieve maximum savings, self-consumption and energy security,
reliable battery storage is essential. We offer several battery architecture choices, each designed for different
installation needs, space limitations and power requirements.
1. Modular 12V LiFePO4 Battery Packs
Individual 12V LiFePO4 modules that can be wired in series and parallel to build a 48V/51V system with
any desired capacity. Lightweight units make installation easy.
Requires a steel mounting rack or shelving for stable stacking and cable management.
- Flexible scaling – build any capacity
- Easy transport and replacement of modules
- Best placed in storage rooms, garages or technical spaces
Ideal for: Homes, farms & commercial use where the battery is installed out of sight.
2. 51V Cabinet Batteries (on wheels)
A clean and compact ready-to-use indoor battery. On wheels and easy to relocate.
Can be placed in living areas thanks to silent operation and modern industrial design —
even without technical rooms.
- Fast installation, no wall mounts or racks needed
- Optional parallel connection for larger capacity
- Suitable for homes, offices, shops
Advantage: Low cost entry + clean appearance. Can also be installed in warehouses or storage rooms.
3. High-Voltage Rack System
A professional rack solution for large installations. Modules are connected in
series under a central management unit, forming a high-voltage battery.
Higher voltage means lower current — thinner cables, less heat, and higher efficiency.
- For high-power inverters and large capacity systems
- Minimal power loss over distance
- Commercial buildings, industrial sites, farms
Note: Requires inverter compatibility with HV battery architecture.
Low-Voltage vs High-Voltage Batteries
| Feature | Low Voltage (48–51V) | High Voltage (100–400V+) |
|---|---|---|
| Current | Higher | Lower |
| Cable size | Thicker | Thinner |
| Heat losses | Higher | Lower |
| Best use | Homes & small business | Large systems & high loads |
4. Lead-Carbon Batteries (Optional)
A cost-efficient alternative to LiFePO4. Improved performance over traditional lead-acid,
longer lifespan, and better temperature tolerance. Heavier and larger, but suitable when the goal is a lower investment cost.
Good for: Budget-optimized systems
Limitation: Higher weight and lower energy density compared with LiFePO4.
The battery is the heart of a solar energy system.
With the right storage, you unlock true self-consumption, price savings, and energy security.
