connectingthebatterymodulestotheinverter.
Donotturnonthemasterswitchonanyofthebatteries
untilallconnectionshavebeencompletedandthe

4. 2. 2. MODULE TERMINAL CONNECTIONS
WheninstallingthemoduleswithPOWERSYNCenclosures
theappropriatemoduletomoduleconnectorswillbe
provided.Ifyourmodulesarebeinginstalledwitha
thirdpartyenclosureorbatteryracking,we recommend
using a 2/0 welding cable for the module to module
connections.
Themodulethatisconnectedtotheinverterisalways
the“HOST”module.Itisrecommendedtoconnectthe
batteriesasseeninFigure2.
1. ConnecttheP1terminalonthehostmoduletothe
positiveterminalontheinverter.ThetheN1terminal
oftheHOSTcanbeconnectedtothenegative
terminalontheinverter.Alternatively,theN2terminal
onthelastmoduleinthestackcanbeconnectedto
thenegativeterminalontheinverter.
2. StartingwiththeHostbattery,connecttheP-2
