Figure 3-11 Basic networking of the parallel off-grid ESS (dashed boxes indicate
optional components)
NO TE
The primary load power does not exceed the max off-grid output power of the Inverter.
Networking 2: Multiple Inverters Cascaded
You can add inverters and batteries to increase capacity. A maximum of three
inverters can be cascaded. Each battery connects to the inverter through an
independent RS485 port and is managed by the inverter connected to it.
SmartLogger Networking
●
SmartLogger V300R001C00SPC100 and later versions are supported in this
scenario. For details about commissioning using the SmartLogger, see
●
Inverters that support batteries cannot be cascaded with those that do not.
For example, SUN2000-(3KTL-10KTL)-M1 (with batteries) and SUN2000-
(8KTL-20KTL)-M2 (without batteries) cannot be cascaded through Smart
Dongle.
●
The grid-tied and off-grid ESS supports cascading of SUN2000-(3KTL-10KTL)-
M1 and SUN2000-(8KTL-20KTL)-M2 or SUN2000-(20KTL, 29.9KTL, 30KTL,
36KTL, 40KTL)-M3.
