The Sonnenschein Solar “Blocks & Cells” batteries stand out thanks to their robust gel-VRLA technology, long life cycles, low maintenance needs, and eco-conscious manufacturing. The SOLAR BLOCK series is excellent for medium-sized solar installations, while the A600 cells cater to high-capacity, long-life requirements.
What Are They?
- Sonnenschein Solar is a premium line of VRLA (Valve-Regulated Lead-Acid) gel batteries tailored for solar and renewable energy systems.
- The term “Blocks & Cells” refers to two sub-series:
- SOLAR BLOCK: Durable, robust battery blocks designed for medium-performance needs (e.g., off-grid homes, industrial solar setups).
- A600 (Cells): 2-volt cylindrical or flat cells for higher-capacity, heavy-duty battery banks, offering exceptional longevity and reliability.
Key Features & Benefits
SOLAR BLOCK Series
- Exceptional cycling performance: Up to 1,200 cycles at 60% Depth of Discharge (C10) at 20 °C.
- Long shelf life: Up to 17–24 months at 20 °C without recharge due to very low self-discharge .
- Robust, maintenance-free design:
- Dryfit® gel technology: Sealed, VRLA gel battery requiring no water topping-up.
- Resistant to deep discharge and harsh conditions .
- Safe transport classification (IATA clause A67), and made for global shipping.
- Eco-friendly: Fully recyclable with low CO₂ footprint .
- Variants and specs:
- 6 V models: SB 6/200 A (200 Ah), SB 6/330 A (330 Ah) .

A600 / 2-Volt Cells
- Superior cycling performance: Up to ~4,700 cycles at 30% DOD (depth of discharge) thanks to tubular plate construction.
- High capacity range: Cells from 285 Ah (C100) all the way up to 3,800 Ah+, enabling very large battery banks.
- Made in Germany, meeting rigorous quality standards and ideal for deployment in demanding renewable energy systems.
Ideal Applications
- SOLAR BLOCK batteries excel in:
- Residential off-grid setups, weekend homes, marine and wind-powered systems, safety equipment, and remote measuring stations.
- Marine navigation aids, due to their long service life and rugged design.
- A600 Cells are suited for large-scale or mission-critical solar installations that demand durability and high capacity (e.g., microgrids, rural electrification projects).
