Huawei LUNA2000-14-S1 Battery Storage 13.8 kWh

Huawei LUNA2000-14-S1 Battery Storage 13.8 kWh

Modular high-voltage storage system with 13.8 kWh lithium iron phosphate capacity – cable-free module connection, integrated heating function, for residential photovoltaic systems.

The Huawei LUNA2000-14-S1 is a modular PV storage system, i.e. a high-voltage battery storage system for photovoltaic installations based on proven lithium iron phosphate technology – ideal for storing solar energy and maximising self-consumption as a home storage system or in commercial installations. The system is based on the so-called Module+ architecture: each battery module has its own integrated energy optimiser that controls the charging and discharging process individually at cell level. According to the manufacturer, this achieves up to 40 % more usable energy as well as a full depth of discharge of 100 % – even if individual modules age differently or have different production dates, the total usable capacity remains at its maximum. The cable-free connection between the modules enables quick and straightforward commissioning without extensive internal wiring. The ESS supports capacity expansion – up to three energy storage modules can be installed per tower. The LUNA2000-14-S1 is exclusively compatible with Huawei SUN2000 inverters.

Scope of Delivery

• 2× Huawei LUNA2000-7-E1 battery module (6.9 kWh each)
• 1× Huawei LUNA2000-10KW-C1 power module
• All necessary connection cables and mounting hardware

Features

• More usable energy: Module+ architecture with energy optimiser per module – up to 40 % more usable energy, 100 % depth of discharge.
• Cable-free module connection: Quick commissioning without extensive wiring between the modules.
• Integrated heating function: Operation from -20°C to +55°C – automatic heating in cold environments, consuming stored energy in the process.
• Low-noise operation: No loud fan required – noise emission below 29 dB.
• Five-level safety concept: Cell-level monitoring, electrical and structural protection, fire suppression within 15 seconds, IP66 underwater protection (40 cm, 72 hrs.) – not designed for permanent contact with water.
• Flexibly expandable: Can be retrofitted with one additional 5 kWh battery module LUNA2000-5-E1 or another 6.9 kWh battery module LUNA2000-7-E1 – capacity per tower expandable up to a maximum of 3 modules or 20.7 kWh, after which no further expansion of the individual tower is possible.

Expansion and Scaling

Up to 3 battery modules can be combined per tower in any combination of the 5 kWh battery module LUNA2000-5-E1 and the 6.9 kWh battery module LUNA2000-7-E1 – the LUNA2000-14-S1 can therefore subsequently be expanded with one additional module, up to the maximum tower capacity of 20.7 kWh (3× LUNA2000-7-E1). In addition, up to 4 complete towers can be operated in parallel, depending on the inverter used – this maximum configuration with 4 towers is, according to the manufacturer, exclusively supported by the SUN2000-MB0 series and enables a total capacity of up to 82.8 kWh per inverter, which is also of interest for larger homes and commercial applications. According to Huawei support, towers in parallel operation may have different capacities. However, combining LUNA2000 S1 with the predecessor series S0 within one storage system is not permitted, neither individually nor in parallel operation – only when operating with two separate inverters can an S0 system be connected to one and an S1 system to the other.

Advantages over the Huawei LUNA2000 S0

Compared to the predecessor series LUNA2000 S0, Huawei has made several key improvements with the S1: the extension modules hold significantly more at 6.9 kWh compared to the S0's 5 kWh, maximum charging/discharging power increases to up to 10.5 kW per tower (S0: max. 5 kW), and the protection rating was raised from IP65 to IP66 – including underwater protection up to 40 cm water depth. The operating temperature range also expanded noticeably, from -10°C to +45°C with the S0 to -20°C to +55°C with the S1. The warranty period increases from 10 to 15 years (on 80 % of performance), and for backup operation, the S1 additionally supports black start capability.

Optional Accessories

For backup power functionality, the Huawei SmartGuard (single-phase / three-phase) with integrated EMMA functionality is recommended for comprehensive energy management and backup supply. Without backup requirements, the Huawei EMMA is sufficient as a standalone HEMS module, for example to make optimal use of dynamic electricity tariffs and get the most out of the system. For those who prefer not to use the included floor stand, the LUNA2000-S1 can alternatively be space-savingly wall-mounted using the separately available wall mounting bracket for LUNA2000 S1.
