The inverter can be monitored via Wi-Fi or GPRS. All Solis communication
devices are optional (Figure 4.21). For connection instructions, please refer to the
Solis Monitoring Device installation manuals.
To protect the inverter's AC grid connection conductors, Solis recommends installing
breakers that will protect against overcurrent. The following table defines OCPD
ratings for the Solis single phase inverters.

1. The RCD should be in parallel connection between the consumers mains and the solar supply.
2. More than one RCD may be used. Each RCD can protect one or more circuits.
Refer to figure 4.22, which is a simple guidance for installing a solar system with PV inverter.
A DC isolator is required to be installed in the system between PV panels with inverter.
4.3.7 Meter Connection(optional)
The inverter can work with a single phase smart meter to achieve Export Power Management
function and/or 24hour consumption monitoring function.
Note:
Inverters are classified as "Meter Model" and "CT Model" due to hardware
difference.Meter Model can only connect a smart meter. CT Model can only
connect a smart sensor.Please consult Solis Sales Rep before placing the order.
Note:
To achieve Export Power Management function, the smart meter can be
installed on either grid side or load side. To achieve 24hour consumption
monitoring function, the smart meter can only be installed on grid side.
Below are the connection diagrams of different meters connecting to different locations.
Detailed settings please refer to Section 6.5.12.
Two types of meters are supported:
Direct Insert Type Meter - Max input current 60A (Model:DDSD1352-C)
External CT Type Meter - 120A/40mA CT is supplied (Model: ACR10RD16TE)
Customer can place the order for a suitable meter from Solis Sales Reps.
