Over the years, Virtue Solaris worked with various top brands of hybrid inverters and battery systems, both on and off the grid. We installed many systems using top brands like Huawei, Sungrow, Growatt, Deye, Dowell and Bluetti, and we’re very conscious of the advantages and limitations inherent in each technology, model and brand.
From our experience, currently, Huawei LUNA2000 battery system offers the best energy storage solution for Maltese households for single phase systems, whilst Sungrow with its SBR battery system and three phase hybrid inverters holds an edge in three phase residential segment. These systems are proven for their technological functionality, unparalleled safety, reliability, efficiency, award-winning design, scalability and overall value for money.
Both Huawei and Sungrow’s solar home battery systems have a scalable, modular design, and are ideally suited as a home grid-connected hybrid battery systems with off-grid power backup.
Huawei system consists of a power module and one or more battery modules with capacity of 5 kWh each. Up to three 5kWh modules can be added to a battery unit, and up to two batteries can be connected on the same system, making capacity scalable from 5kWh to 30kwh. Two batteries can be integrated in parallel in one solar panel installation. This allows a maximum storage capacity of 30 kWh per inverter.
Sungrow’s batteries start at 9.6kWh, and feature modular increase in units of 3.2kWh each up to 25.6kWh.
The LUNA2000 battery module is suitable for use with both single- and three-phase Huawei inverters, and likewise, Sungrow’s SBR batteries work with Sungrow’s three phase and single phase hybrid inverters.
Both systems are safe and reliable thanks to the lithium iron phosphate (LFP) battery cells. Defective battery modules are automatically isolated so that the system can continue to function.
Huawei hybrid inverter and battery can be integrated with a backup box, which provides backup power in case of power cuts, whilst Sungrow hybrid inverters feature an in-built backup capability, which does not require external backup boxes. For three phase systems, Sungrow currently holds advantage over Huawei, since its range of 3 phase hybrid inverters is capable of providing backup power across all 3 phases, whilst Huawei 3 phase system is presently only capable of single phase output in backup mode.
All components of the system can be monitored and controlled through a smart management app, which displays a wide variety of data that can also help households to make informed decisions about their energy use.
