  • Lighting control options:

This solar charge controller is ideal to manage a battery pack but is also designed to switch a 12 or 24V load. The 10A and 20A controllers detect when the solar panel stops generating energy and will switch on a connected load accordingly. The 30A controllers has a light sensor and will switch the load on when darkness falls.

Load control programming:*
Display Work mode (SP=Solar Panel) Display Work mode (SP=Solar Panel)
'0' LOAD is on all night when SP inactive  '9' LOAD ON for 9 hour after SP inactive
'1' LOAD ON for 1 hour after SP inactive '0.' LOAD ON for 10 hour after SP inactive
'2' LOAD ON for 2 hour after SP inactive '1.' LOAD ON for 11 hour after SP inactive
'3' LOAD ON for 3 hour after SP inactive '2.' LOAD ON for 12 hour after SP inactive
'4' LOAD ON for 4 hour after SP inactive '3.' LOAD ON for 13 hour after SP inactive
'5' LOAD ON for 5 hour after SP inactive '4.' LOAD ON for 14 hour after SP inactive
'6' LOAD ON for 6 hour after SP inactive '5.' LOAD ON for 15 hour after SP inactive
'7' LOAD ON for 7 hour after SP inactive '6.' LOAD ON/OFF when pressing button
'8' LOAD ON for 8 hour after SP inactive '7.' Test mode: LOAD ON when inactive, OFF when active
  • *There is a 10min delay, to prevent unwanted switching on and off, before the output gets activated.
