In short Cold mornings and a battery that will not take a charge, or a cell fault nobody notices until it is too late - those are the two failure modes that matter in home storage. The LIONSHEE LS-L2048 answers both with options: automatic low-temperature heating and a built-in fire extinguisher. Underneath sits a 2048 Wh A+ grade LiFePO4 pack rated for 6000 cycles behind an IP65 housing. Shipping from our German and UK warehouses. |
6000 Charge cycles | IP65 Protection grade | 2048 Wh Nominal capacity per unit | 6144 Wh Maximum with 3 units in parallel |
The LS-L2048 stores the solar energy a household produces during the day so it can be used in the evening instead of being fed back at a low tariff. The enclosure measures 320 x 200 x 346 mm and weighs 18 kg, compact enough to stand under a window or against a wall, with a recessed carry handle for moving it into position. Cooling is passive: no fan, no running noise. Battery communication runs over CAN and RS-485.
Optional low-temperature heatingLithium iron phosphate cells must not be charged below freezing. The optional automatic low-temperature heating warms the cells first, so the battery still accepts a charge in cold climates. Charging range 0~55 °C, discharge range -20~60 °C. |

Optional built-in fire extinguisherAn automatic fire extinguishing unit can be built into the enclosure. It acts inside the box, at the cell level, without waiting for someone to notice a problem - relevant wherever the battery sits close to living space. |

2048 Wh from A+ grade EVE LiFePO4 cellsOne Power Box stores 2048 Wh at 51.2 V nominal, with a working voltage range of 40~58.4 V. The A+ grade EVE LiFePO4 cells stay stable over a long service life, which is what makes 6000 cycles and a 5-year warranty possible. |

IP65, natural cooling, 18 kgThe housing is rated IP65 against dust and water jets and is cooled passively, so there is no fan and no running noise. At 18 kg and 320 x 200 x 346 mm it stays a single floor-standing box with a carry handle, no rack or wall frame needed. |

Expandable to 6144 Wh, one module at a timeUp to 3 units can be connected in parallel for a total of 6144 Wh. Customers can start with a single Power Box and add modules as consumption grows, instead of paying up front for storage capacity that is not yet needed. |
On-grid, off-grid and portableThe same unit works in grid-connected solar self-consumption, in off-grid systems and as portable outdoor power. It is also the storage module of the LIONSHEE Modular Balcony Energy Storage System, alongside LS-240W flexible panels, the LS-H1600 Smart Solar Hub and 800 W, 1600 W or 2000 W microinverters. |
