Plasmatronics PL20 PWM Solar Controller for 12-48v Systems - Lithium Compatible (user programmed)

Max. Solar Currant: 20A

The PL series of charge controllers give you the freedom to operate your solar electric system the way you want to.

They offer complete control over the charge cycle, plus an unprecedented amount of useful information about current and past performance.

PL regulators help to protect the system with a built in low battery disconnect switch. In addition, the versatile event controller can switch power on or off according to criteria set by the user. This allows the PL to do extra tasks such as switching a light on at night or keeping a water tank full by operating a pump when needed.

The user can select either Pulse Width Modulation or slow speed switching. Regulation can be done in both series and shunt modes. Other features include backup generator control and charging a second battery.

The PL Series is designed for Caravan / Motor-home / Camping systems, as well as Commercial and industrial stand alone applications.

Features:

• Adjustable: All settings are adjustable, and are stored in non volatile memory so you don’t lose your custom set up if the unit needs to be disconnected from the battery.
• Display: User friendly LCD display. Each number has a label.
• Energy metering: Daily Load and Charge Ah plus State of Charge, all recorded for 30 days.
• Four Stage Regulation: Boost, Absorption, Float, and Equalisation available as appropriate for the battery type.
• History: Records Charge and Load Ah, Max and Min battery voltages, SOC, and Float times for the last 30 days. You can tell how much energy was really collected and used. This history can be very useful when diagnosing a system problem.
• Generator Control: A sophisticated generator controller is included, with four different modes of control, and a quiet time option.
• Event Control: A powerful event controller/timer allows the Load and/or General Purpose terminal to turn on or off a wide range of loads (e.g. pumps, lights, motors etc.), under a user specified set of conditions.
• Alarm: There is an adjustable high or low battery voltage alarm output, which can drive an external alarm device.
• Second Battery: When the main battery is full, the PL can supply a signal to switch a relay, so that some or all of the array can charge a second battery. The second battery charging is also controlled.
• Remote control: The PLM remote display allows all functions to be accessed from up to 100 metres away. Fits in a standard light switch mounting plate.
• Data Comms: Communication with a computer is possible via the optional PLI interface. This allows fast downloading of all data and adjustment of settings. Can be used via a modem for remote sites etc.
• Protection: Protected against short circuits, reverse flow, and lightning. Low battery load disconnect function built in. Current limiting in the event of over temperature or over current. Full conformal coating protects against corrosion.
• External Shunts: Up to two external shunts can be added using optional DC isolated PLS2 shunt adaptors. Inverter and/or battery charger current and other external currents can be included in the Ah readings and SOC.
