Operation and Construction
Load delay shutdown up to 24 hours and manual load switching. Maximum PV open-circuit voltage: 50V. The controller uses a black plastic housing with an aluminum heat sink base and an LCD display.
Dimensions: 184 × 93 × 50 mm. Operating temperature: −10°C to +45°C. Protection rating: IP21.
System Selection and Installation
Select the model according to charging current, battery voltage and load requirements. Set charging parameters to match the battery manufacturer’s requirements. Connect the battery first, then the PV panel, and finally the DC load. Match the solar panel voltage to the battery system and keep PV open-circuit voltage within the controller limit.
