Finn's Canadian Solar Inverters Review & Verdict
Finn Peacock has been a Chartered Electrical Engineer since 1998, and is ex-CSIRO
Canadian Solar panels are great, but I wouldn’t choose a Canadian Solar inverter. Let Canadian Solar do what they do best – solar panels – and buy your inverter from a proper inverter manufacturer.

Company Info
Canadian Solar has two business segments: CSI Solar and Recurrent Energy. It's CSI Solar that manufactures solar components such as solar modules, battery energy storage systems and inverters.
Despite the "Canadian" in the name, Canadian Solar's inverters used in home solar installations are manufactured in China. That's not a bad thing, just worth knowing.
Canadian Solar Inverters - CSI-xK-S22003-E Series
The company offers CEC-listed dual-MPPT single phase string inverters in Australia in capacities of 5kW and 7 - 9kW, offering maximum efficiencies of 98.1%. The operating temperature range is -25C ~ 60C. Over 45C and the inverters begin to derate, which is the controlled reduction of inverter power to protect sensitive components.
The inverters measure 355 x 435 x 158 mm and 399 x 446 x 192 mm; weighing in at 13.5 kg and 19.5 kg
Monitoring is offered via CSI Cloud, which allows users to keep tabs on system performance and key metrics. CSI Cloud is available via web portal or a full-featured mobile app.
Update 24 January 2025: The Clean Energy Council has suspended several Canadian Solar (CSI-Solar) inverter models from its approved solar products program.
Update: 30 January 2025: The CEC has lifted the suspension on all 4 models and withdrawn its intention to suspend another.
Warranty Information
The single phase inverters mentioned above are covered by a 5 year parts and service warranty, with a free 5 year extension when the product is registered online. An extension of up to 20 years is available for an extra charge, but this only covers parts and not labour.
The warranty for accessories such as Wi-Fi data loggers and energy meters is 2 years.
