- My bluesolar 75/15 streetlight function correctly turns on the load at the sunset voltage but it seems the delay time I put in is ignored? My load is set to "always on" and streetlight is set to sunrise 26v and sunset 4 volts. Sunset stay on until sunrise with the delay for sunset set for 15 minutes. The load is turned at sunset voltage with no delay when voltage is reached... What am I doing wrong? Thankyou
