PWM Solar Controller

Ferris Solar Monitor & Regulator - SMR

The Ferris SMR is an easy to read, flush mounted solar charge control that displays the charging current of your solar panel(s) while protecting the battery(s) from overcharge. The full scale ammeter provides charging current readout, at a glance. The SMR is available in a 5 and a 10 amp format. Both SMR's have dual isolated outputs. This unique feature allows you to charge two separate battery(s) or battery banks at the same time, while keeping them electrically isolated. Years of proven reliability, ease of installation & low cost make the SMR an industry favorite.

An optional surface mounting box is available.
