Introduction - Projecta IntelliJay PM300-BTJ Instruction Manual

1. INTRODUCTION

PM300-BTJ and PM335J-NODE are power management systems designed for use in caravans or motor homes.
These systems allow for easy installation and a user-friendly interface.
Both PM300-BTJ and PM335J-NODE systems come with the same PM335J transformer unit, which the circuits in the caravan
or motor home are centrally wired to. This transformer features built-in battery charger, power supply, fused distribution
blocks, MPPT solar charge controller, voltage charging relay (VSR), low voltage disconnect (LVD), water pump controller, hot
water system controller, water tank indicator and battery monitoring.
The main difference between the two systems is that PM300-BTJ comes with an Bluetooth-enabled LCD screen (PMLCD-BTJ),
allowing a user to monitor and control the system via the LCD or the Bluetooth app. PM335J-NODE does not come with an
LCD screen, instead utilising a separate Bluetooth node (PMBTJ-02) to connect with the Bluetooth app.
