Sentinel Solar info

Solar Charge Controller

Solar charge controller with internal microprocessor providing optimal charging current and voltage. The charge controller includes 3-stage (Bulk, Absorption & Float) charging with temperature compensation ensuring correct maintenance of the internal lead acid battery and maximising the service life of the battery.

The solar charge controller also includes low voltage cutoff protection to preserve the battery and to protect other system conponents from powering on below the required voltage.

Our solar systems use a 12V internal power circuit which means they are very safe to use and do not require an electrician for installation or maintenance.

The systems include an 8-day programmble digital timer to manage auto on/off times for system power. 

Monocrystalline Solar Panel

These monocrystalline silicon solar panels are designed for long life (up to 25 years) and high efficiency output. An excellent solution for remote or mobile power applications. Aluminium frames and tempered glass panels allow installation in demanding environments. To prevent moisture ingress, the solar cell modules are protected by a sheet of 3.2mm tempered glass. Operating temperature -40°C to 85°C.

Lead Acid Battery

Sealed, non spillable 20 Amp/Hour Lead Acid Battery.

It is highly recommended that the Sentinel range of systems are used only for 12 hour daytime applications. Although the 20A/H battery in the system will generally keep a system running throughout a full night when fully charged, these systems will not sustain permanent 24 hour usage throughout all weather conditions.
