Plasmatronics PL Series - Intelligent Regulators

Plasmatronics PL series regulators

The Plasmatronics PL series of charge controllers give you the freedom to operate your solar electric system the way you want to. PL series regulators have been used in thousands of off-grid solar systems and earned a reputation for versatility and reliability.

The four stage charging algorithm incorporating true Pulse Width Modulation (PWM) constant voltage control gives you complete control over the whole charging cycle. All charging voltages and times are adjustable over generously wide ranges. This allows you to customise the charging regime to suit just about any custom requirements which you (or your batteries) may have. In most cases you can choose from one of our four default programs, which are suitable for most types of batteries and systems.

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.


Display shows battery voltage, charge current, ampere hours in and out of battery, load being drawn from the battery and which part of the charge cycle the battery is in.

Easy to Maintain
Information is available for the past 30 days - so even if the user doesn't remember what happened, the regulator will.

Well Connected
With the optional PLI interface and PLcom software, the user can access the regulator from a computer. Data can be read or settings adjusted. This can be done remotely using a modem.

It may be the only regulator you will ever need to stock. Its capacity to handle 12, 24, 32 and 36V systems and allow complete control of the regulation cycle mean you can use it almost anywhere.

All settings are adjustable and are stored in a non volatile memory.

User friendly alphanumeric LCD gives you words to explain the numbers.

Energy Metering
Shows daily charge and discharge amp hours.

Three Step Regulation
Boost, Absorption and Float modes with an optional periodic Equalisation mode. Can switch in series, shunt or series + shunt modes.

Records charge and load amp hours, max and min battery voltages and state of charge for the last 30 days. Remembers how much was really collected and used.

Generator Control
A sophisticated generator controller is included with four different modes of control available and a quiet time option.

Event Control
A versatile event controller allows the load to be turned on or off under a user selected set of conditions. Can be used for lighting, pumping, frost control etc.

There is an adjustable low or high battery voltage alarm.

Second Battery
When the main battery is full, use the waste energy to charge an auxiliary battery. The PL supplies a signal to switch a relay to the second battery.

Remote Control
A computer can communicate with the PL using the PLI RS232 interface. Data can be downloaded and settings adjusted from far away.

Protected against short circuit and reverse flow. Adjustable low battery DC load disconnect function available. Current limit for over heat or over current. Conformal coating applied to protect against corrosion.

External Shunts
Two external shunts can be connected using the DC isolated PLS2 bi-directional shunt adaptor.

We install solar systems in Northern NSW and Southern QLD.

Gold Coast (from Coolangatta to Southport), Nerang and Hinterland (Beaudesert) and out West (Warwick, Stanthorpe, Killarney)

Northern NSW (Tweed Heads to Yamba, including Evans Head, Byron Bay and Ballina); the Far North Coast Hinterland (Grafton via Lismore to Murwillumbah) and out West (Casino to Tenterfield, including Drake and Tabulam, as well as Woodenbong and Bonalbo)

For larger system we also go up to Brisbane or down to Coffs Harbour and even Glen Innes. Other places by arrangement.
