GOD BLESS AND LET’S GO SOLAR!!
Neste vídeo mostro alguns picos de amperagem do meu painel photo voltaic Canadian de 260w através do controlador automático (12v ou 24v) PWM Solar30. Em breve publicarei mais vídeos com o sistema que ainda é incipiente. Boas sugestões e dúvidas serão bem-vindas. Obrigado!
