Without a remote temperature sensor, lead-acid batteries may undercharge or overcharge de-
pending on the ambient temperature of the installation environment. This may result in a fire
hazard.
Depending on the battery type, the inverter should be capable of controlling the
batteries BMS. Therefore, you need to set the protocol of the BMS on both the bat-
tery and the inverter.
When using more than one battery, the first battery will be the master, and the other
batteries will be the slaves. Please, check the battery manufacturer specification
for proper operation.
To verify if the battery is actually communicating access the Li BMS menu as de-
tailed in section 4.13 ‘Setting Up a Lithium Battery’ and check whether the values
are realistic or not. It is important that the charge and discharge limits in that page
match the numbers expected for the number of batteries physically connected.

GRID
This works like a conventional grid-tied inverter. It is both an input and
output connection for non-essential load and supply
LOAD
Connection of essential loads such as lighting, security systems, and
Internet
Before connecting to the main grid, please install a separate AC Breaker (MCB) between the
inverter and the grid. In addition, it is recommended the installation of an AC Breaker between
backup load and inverter. This will ensure the inverter can be disconnected safely during main-
tenance and fully protect the system from over-current. The recommended AC Breaker is 20A
for 8kW, 32A for 10kW and 32A for 12kW.
There are three terminal blocks marked as GRID, LOAD, and GEN. Please do not confuse input
and output connections.
All wiring and cable sizes must comply with your particular country’s wiring regu-
lations and Codes of Practices. Ensure that suitable disconnection devices and
RCDs are fitted.
