Solar generation ready for energy storage
Huawei SUN2000-5K-LB0 is a single-phase hybrid inverter rated at 5 kW for residential solar generation. Two independent MPPTs support one or two appropriately designed PV strings. Built-in WLAN, RS485 and FusionSolar support generation monitoring. Its battery interface allows a compatible LUNA2000 storage system to be added as a separately selected system component.
Two MPPTs matched to the roof
For SUN2000-5K-LB0, the manufacturer recommends up to 7500 Wp of PV. Two MPPTs each provide one string input, with 16 A input and 20 A short-circuit limits according to the actual nameplate version. One or two array branches are designed around orientation, operating voltage, series module count and cold open-circuit voltage.
PV voltage design
MPPT operates over 40–560 V, with 360 V nominal input and 50 V start-up voltage. Maximum DC voltage is 600 V. Series module count is checked against cold open-circuit voltage and the actual input-current limit. Compatible optimizers can be incorporated according to their exact family, firmware and approved layout.
Output for a single-phase system
The 5 kW rating combines with 5500 VA maximum apparent output and 25 A maximum output current. The inverter connects to a suitable single-phase system at 50 or 60 Hz. Maximum efficiency is 97.8%, with 97.1% European efficiency. Grid profile, power and power-factor settings follow the actual connection requirements.
LUNA2000 storage as part of the assembly
Supported systems include LUNA2000-5/10/15-S0 and LUNA2000-7/14/21-S1 according to the current specification and appropriate configuration. Battery modules are combined with the correct power and control module for their generation. Capacity in kWh follows the selected complete battery; inverter output in kW describes a different property. Protection, communication and firmware form part of the design.
Charging from solar and grid
The battery interface supports charging up to 6 kW and model-specific discharge up to 5500 W. Maximum battery current is 16.5 A; the current manual specifies a 350–580 V DC interface. Actual output also depends on the compatible complete battery and its state. Grid charging, schedules and self-consumption are configured with metering and connection rules.
Grid backup and independent island projects
Home backup can be designed with a compatible battery and SmartGuard-63A-S0. The current manual also supports independent off-grid operation in a direct configuration without a 4G Smart Dongle, WLAN-FE Smart Dongle or SmartAssistant. A professional designs island circuits and their separation from the grid for the actual assembly. Rated island apparent output is 5000 VA, with 110% support for 10 seconds. Load selection accounts for simultaneous demand and start-up.
FusionSolar and system communication
Built-in WLAN and RS485 provide local and system connections, with FusionSolar plant visibility. Ethernet uses a separate WLAN-FE Smart Dongle, while mobile data uses a compatible 4G Smart Dongle. The current manual describes up to two ESSs per inverter according to the approved configuration. Up to three cascaded inverters belong to an appropriate SmartAssistant or Smart Dongle network; SmartGuard backup networking is designed separately.
Compact outdoor design
IP66, natural cooling and a −25 to +60°C operating range support permanent installation at a home. The current manual specifies a maximum 15 kg weight and dimensions of 425 × 376.5 × 150 mm including mounting parts. Typical noise is below 29 dB. Provide suitable airflow and service access; operating altitude reaches 4000 m with power management above 2000 m.
Protection and connection preparation
Integrated insulation, residual-current, arc-fault and grid monitoring complements power-path protection. The manual gives 32 A reference AC protection for this model. A professional designs cables, surge protection, earthing and distribution-board connection for the actual project. Supported grid systems are TN-S, TN-C, TN-C-S and TT with appropriate protective measures.
Selecting the exact assembly
Base a recommendation on the exact SUN2000-5K-LB0, connected-circuit demand and required battery capacity. This item offers the inverter as an individual component; battery, metering, network accessories and backup transfer equipment are selected as appropriate project components. The public Batterado profile and Markdown retain the stated parameters and system relationships. Estimated delivery of 2–3 days is a seller estimate.
