Huawei are the World’s largest solar inverter supplier (latest report 2018) with 22% market share.
Sungrow (15%), SMA (8%) are second and third.
In Australia, Huawei released a range (2kW to 5kW) of single phase hybrid residential inverters in January 2018 (SUN 2000L brochure) and added a 5kW three phase hybrid inverter in October 2019 (SUN 2000 M0).
The single phase Huawei hybrid inverters all have battery inputs, and are plug and play ready to connect LG Chem RESU 7H and LG Chem RESU 10 HV batteries (400V).
The single phase Huawei hybrid inverters support both a single or three phase Smart Meter to allow connection to both single and three phase supplies. This provides both consumption reporting in the software but also the information needed by the inverter to store or release battery power.
The three phase Huawei hybrid is released also with the battery inputs, but at time of release, are not immediately able to connect to a battery as further testing continues. Battery support is expected second half 2020.
The warranty on both the single and three phase Huawei hybrid inverters is 10 years parts AND labour.
This can be extended to 15 years parts and labour for an additional $300 and 20 years parts and labour for $600.
DC Optimisers are available for Huawei inverters but are optional. Optimisers can be used where there are risks of power losses from shading, or where there is a need to install panels on additional roof orientations that exceed the built in inverters 2 x MPPTs. Optimisers can be installed on all, or any panels, or none at all, as required.
The optional Huawei Smart PV Safety Box, used in conjunction with Huawei optimisers provides panel level monitoring within the Fusion Solar reporting software (Smart phone app, and Web Browser) as well as instant shutdown of any optimised panels if required during maintenance.
Huawei have priced the inverters to compete strongly against those offered by Fronius, SMA and SolarEdge.
Although there are no official recommended retail prices in the Australian solar industry it is typical to find 5kW Fronius single phase inverters (Primo and SC models) at $2,100 to $2,200. The single phase Huawei inverters is typically $1,700 to $1,800. The Fronius is not a hybrid (battery) inverter, Huawei is.
The new Huawei three phase 5kW hybrid is $1,900 to $2,000 compared to the non hybrid version of Fronius (Symo) at $2,300 to $2,400 but is much lower cost than the Fronius single MPPT hybrid model at $3,200 to $3,300.
The Huawei hybrid inverters are small and light and have a patented passive cooling system, and no noisy fans, and tests show that there is zero de-rating of the Huawei inverter even when the internal cabinet temperature reaches 70 degrees centigrade.
The reporting software, recently changed from NetEco to Fusion Solar is comprehensive for both users and installers alike. The setup of the inverter is easy using the wizard in the Fusion Solar setup application as is the creation of an account within the Fusion Solar domain
Technical support for Huawei solar inverters is available by phone (1800 046 639) or by email . In either case a support ticket is created and the inverter support team who are mostly based in Europe are competent and responsive.
