Sunsynk 3.6kW AC 7kWp ECCO Hybrid Inverter (SG04)


Considered the Swiss army knife of inverters the SunSynk 3.6kW ECCO 7kWp hybrid is unique in that it can charge and generate at the same time. Also, by connecting up to 7kW’s of PV to a single unit, the device can export 3.6kW whilst at the same time using the surplus to charge batteries – therefore generating power as well as charging.

The 7000W MPPT and rated AC output of 3.68 gives a system that can generate sufficient energy in winter months to offset usage and charge a connected battery.

Additional features:

Dual MPPT design
Compatible with Lithium-ion batteries and Lead Acid batteries
5-year warranty as standard
IP65 rated
Anti-islanding protection
Fully programmable power export
Automatic switching from Grid-Tied to Off-Grid mode
Up to 16 units with the same firmware can be paralleled.

TIP: Quote this inverter for larger houses that can take more than 4kWp of PV and where higher power grid connection is an issue.


IMPORTANT: installers shouldn’t use CT to achieve anti reflux function for MIC750-3300TL-X inverters. Instead they should use the single phase meter Growatt SPM.

Growatt has confirmed that although the use of CT is mentioned in the user manual, because issues have been found with this type of option, they decided to stop promoting CT for limitation to the grid altogether. Therefore, now they recommend the use of the Growatt SPM ONLY for that purpose.
