I use the bathtub analogy to simply explain how to size a solar system. Then I run a simulation for a rainy week
Сейчас посмотрим какая погрешность измерения контроллера заряда аккумуляторов от солнечных батарей Solar 80. Мне было интересно насколько ошибается или врет контроллер. Как выяснилось в ходе эксперимента, прибор действительно имеет некоторую погрешность измерения, которую необходимо учитывать в ходе настройки напряжения отключения заряда аккумуляторных батарей. Жмем лайк и подписываемся на канал!
