TL;DR
Huawei FusionSolar includes inverters, batteries, optimisers and control tools. SUN2000, LUNA2000, EMMA and SCharger span several generations. Confirm exact compatibility and the functions included in your quotation.

Capacity and expansion options depend on the battery. For example, the Swiss LUNA2000-S1 datasheet lists usable capacities of 6.9, 13.8 and 20.7 kWh, with compatibility and parallel-operation conditions. A value for the S0 generation must not be copied to S1. Control functions also depend on interfaces and software versions.

The quotation must identify models, single- or three-phase connection, permitted power and accessories. Request a diagram for solar, battery, grid and backup flows, then confirmation from the network operator. Keep electrical compliance, commissioning and Pronovo documents separate. The supplier must confirm equipment availability and local service.
Our Verdict
Assess the proposed configuration against your roof and consumption. Compare total cost, useful generation, controls and service. An Enphase comparison should use two systems designed for the same shading, uses and storage needs.
Comparisons involving Huawei
Request the complete model code and local network conditions. Phase count, AC power, PV inputs and battery compatibility must be checked for that model.
Confirm the generation, permitted modules, maximum capacity, software and connection requirements. Also ask whether extra components and recommissioning will be needed.
It depends on supported models and interfaces. Document the connection, available modes, limits and behaviour after communication loss; arrange a commissioning test.
The brand alone does not decide compatibility. The installer must check cold-weather voltage, current, power, string configuration and connectors against the selected SUN2000 limits.
Ask about privacy terms, access rights, data export and local functions available without connectivity. Consumption data can relate to an identifiable person; check account and service terms.
Use the same layout and load profile. Compare shading losses, power, battery, backup, monitoring, maintenance and total price with equivalent service commitments.
Sources & method
Manufacturer references for the technologies and products described. Use the datasheet, manual and contract applicable to the model supplied in Switzerland. Confirm versions, availability and functions with your supplier.
