PR6 is a self-contained encapsulated low power consuming shunt regulator for easy fitting to solar panels junction boxes without the need for any additional enclosures.

• PR6 is potted in clear silicon inside the back of the solar panel junction box suitable for the marine environment.
• PR6 provides the field technician with steady green LED indication when panel is shunting (battery full).
• PR6 fits inside junction box of Solar panels from 20 to 80 watts.
• Green LED flashes when panel is charging battery to provide field technician with confirmation of system status.
• Standard shunt voltage set to 14.6 @ 20 degrees Centigrade with re-connection at 13.5 volts. Other settings possible to order.
• All tails provided with identification and crimp connectors fitted.
• Once fitted in the junction box, solar panel tails may be directly connected to battery without the need for any other protection or interconnection.
• PR6 is ideal for single panel beacon or pile applications where interconnection access is limited or denied to unauthorised personnel.
• Where buoy applications requiring 2 solar panels or more the PR8 or PR12 regulators are recommended (see over and following).
• Where LCD indication of system status is required the PR30 is recommended.
• PR6 is fitted as standard to our range of self contained Stainless Steel PS20/100 and upwards to create an efficient well engineered package for site with difficult access while still providing max. information to the field technician.

PR8 is panel mounted pulse width regulator with built-in indicators and terminal block.

PR8 shown here in weatherproof enclosure

• PR8 fits neatly inside its own weatherproof enclosure or can be combined with Station monitoring cubicle.
• Self contained Pulse Width regulator with built in 10 amp fuse load protection which is easily exchanged or removed for maintenance checks.
• Built-in green LED lights to provide easy indication that solar energy is present. Light flashes to indicate PR8 is charging.
• Built in multicolour LED indicates state of charge by colour without need of additional meters.
• When fitted inside clear covered enclosure state of system can be monitored visually with out opening system to the marine environment.
• Optional standard PR8 (only) IP67 enclosure measures 125 x 175 x 75 mm deep with 4mm fixing hole centres of 110 x 160mm.
• Option for automatic disconnection of load when battery reaches a constant 11.1 volts to protect battery from severe damage by deep discharge.
• Option for automatic reconnection of load when solar panel restores battery above 12.6 volts.
• PR8 designed to operate between -25 degree and + 50 degrees centigrade makes the unit very versatile in different environmental conditions.
• Automatic temperature compensation of 3 milli volts / K/cell provides best charge voltage for the battery.
• Can be used on nominal 12 or 24 volt system without need for separate unit. When used on 24 volt system voltage indications should be doubled.
