Introducing DahSolar LVWES05‑G1 and LVWES15‑G2 batteries – premium energy storage now at PV Solar St

The LVWES05‑G1 and LVWES15‑G2 low‑voltage batteries are built on lithium‑iron‑phosphate (LiFePO₄) chemistry and are engineered for safety, long life and flexible scalability. These all‑in‑one batteries are now available for fast delivery in pallet or container quantities, offering installers and project developers reliable storage solutions at competitive prices.

LVWES05‑G1 – compact power for home and small business systems

The LVWES05‑G1 is a compact 5.12 kWh module designed for households, micro‑businesses or modular projects where space is limited. Key features include:

• High safety performance – the battery uses A‑grade LiFePO₄ cells and a smart BMS; optional fluorine‑ketone fire‑extinguisher integration adds another layer of protection
• Long service life – the cell chemistry and balancing design deliver over 6,000 cycles (70 % state‑of‑health), while the recommended depth of discharge remains at ≤ 90 %
• Convenient and smart monitoring – built‑in Bluetooth/WiFi connectivity allows real‑time monitoring and remote firmware updates via the DahSolar app; installer protocols can be configured via the wireless link and battery modules automatically network together
• Flexible installation – the unique dual‑positive/dual‑negative terminal design enables direct stacking and parallel connection without additional busbars. The module weighs only 47 kg and measures 480 × 500 × 155 mm, so it can be wall‑mounted or floor‑mounted.

The technical data show a nominal voltage of 51.2 V, with an operating range of 43.2–58.4 V. Up to 16 units can be paralleled, giving designers flexibility to build systems from 5 kWh up to 80 kWh. Recommended charge/discharge current is 50 A (100 A maximum), and the battery carries an IP20 enclosure rating for indoor use. With CAN 2.0 and RS485 communications, the LVWES05‑G1 is compatible with major inverter brands including SMA, Victron, SolarEdge, Deye, Solis, GoodWe, Growatt and LuxPowerTek. A 10‑year warranty and certifications (IEC 62619‑CB, CE and UN38.3) provide additional peace of mind

LVWES15‑G2 – high‑capacity module for commercial applications

For projects requiring larger capacities, DahSolar offers the LVWES15‑G2 (also known as the 15 kWh “second generation”). This module triples the storage of the smaller unit while retaining the same nominal voltage and communication interfaces. Highlights include:

• Enhanced safety and environmental protection – A‑grade LiFePO₄ cells are housed in a rugged IP65‑rated enclosure (suitable for indoor or outdoor use) with multi‑level BMS protection and an optional pre‑installed fire‑suppression system.
• Extended cycle life – the battery is rated for ≥ 8,000 cycles (70 % state‑of‑health), making it a long‑term investment for commercial or industrial systems.
• Convenience and smart control – Bluetooth/WiFi modules support real‑time monitoring, remote software updates and wireless configuration. Automatic networking simplifies the commissioning of multiple batteries.
• Flexible and scalable – the modular design allows up to 16 LVWES15‑G2 units to be paralleled. Each cabinet stores 14.34 kWh of energy and delivers a nominal 51.2 V with a recommended 140 A continuous charge/discharge and 200 A maximum current. The battery dimensions of 535 × 710 × 235 mm and weight of 115 kg facilitate both wall‑mounted and floor‑mounted installations. Caster wheels are available for ease of movement.

Thanks to the IP65 rating and C5 corrosion protection, the LVWES15‑G2 is suitable for harsh outdoor environments. The battery communicates via CAN 2.0 or RS485 and is compatible with the same wide range of low‑voltage inverters as the 5 kWh module. A 10‑year warranty and certifications (IEC 62619‑CB, CE and UN38.3) underline its quality and reliability.
