CMS solar inverters reviews

Founded around 2007, Carbon Management Solutions (CMS) was an Australian owned and managed solar business supplying components such as inverters for residential and commercial applications. While designed and engineered by CMS, Their inverters were manufactured  by a Taiwanese contractor.

Carbon Management Solutions reportedly went into voluntary administration in 2013, but re-emerged from the ashes like a phoenix under another name - Carbon Management Solutions Group Pty Ltd. That new entity didn't last all that long - ASIC notes it was deregistered in 2018.

The CMS website remains active in 2025, but appears to have been taken over by spammers, so you won't find any useful information there.

CMS Inverters

As well as standard grid connect inverters, CMS also offered the "Smart Series" under its new entity, heralded to be the next generation in innovative inverter technology. These inverters were able to monitor both household consumption as well as production of solar electricity. It was claimed the monitoring system could store up to three years’ worth of data, with the logs accessible via an ethernet or WiFi connection.

CMS inverters were available either in single- or three-phase, in capacities ranging from 1.5kW to 10kW.

Warranty Information

Carbon Management Solutions offered up to a 10-year inverter warranty. But when it liquidated in 2013 and re-emerged under a new name, it reportedly would not honour warranties issued under the previous company. And as the new company also folded, the only hope for a warranty claim for the newer CMS inverters (if any still have coverage) is through whichever company installed them.

It would be surprising if any of these inverters are still installed and operating today - and repairing a CMS inverter that has failed could be a challenge. Consider putting that cash towards a good inverter from another brand more likely to be around for the long haul.
