1. GOODWE your solar engine Instruction of GoodWe ARCB Device Abstract This Document is a brief instruction of GoodWe ARCB Device which compose of Definition Application Background Function Connection Configuration Definition ARCB means Anti Reserve Current feeding into Grid Box CT Current Transfer Application Background As the requirements of some Countries or its areas the generation of the PV systems can only be used in self use but the reserve current cannot be fed into Grid Now the main solution is to cut off the connection of PV system and the Grid but the owner of the PV station will lost a lot of money Such as a 50kW PV system in Australian if the Loads is 20kW but the system can generate 40kWh per hour now then if we just cut off the connection we will lost 20kWh electrical power Also the owner has to turn on the system manually Then GoodWe designed a ARCB device which can tell the inverters to reduce or increase the generation if needed Function As below picture shows The Loads are supplied by PV station and the Grid then PL Pg Pi If we want to make sure no power fed into Grid caused by too many generation of PV System we just need to make sure there always has power comes from Grid So we can monitor the Pg to tell when the inverter need to reduce generation Where the sun shines there 1S Good We GOODWE POWER SUPPLY TECHNOLOGY CO LTD ADD No 189 Kunlunshan Rd SND Suzhou China T2.
