General precaution

DO NOT expose to dust, rain, snow or liquids of any type, the inverter is designed for indoor use. DO NOT block off ventilation, otherwise the Inverter Charger could overheat.
To avoid fire and electric shock, make sure all cables selected are the right gauge and all connections are tight. Smaller diameter and damaged cables are dangerous and could risk fire.
Please do not put any flammable goods near to inverter.
NEVER place unit directly above lead acid batteries, gases from a battery will corrode and damage Inverter Charger.
DO NOT place battery on top of Inverter Charger.

Precaution regarding battery operation

If battery acid makes contact with your skin use plenty of water wash the acid off. If acid goes on your clothes remove these clothes. If irritation to the skin occurs see medical advice.
Lead Acid batteries may generate flammable gas during charging. NEVER smoke or allow a spark or flame in vicinity of battery.
DO NOT place metal tools on the battery, a spark may occur and a short circuit might lead to explosion.
REMOVE all personal metal items such as rings, bracelets, necklaces, and watches while working with batteries. Batteries can cause short-circuit current high enough to make metal melt, and could cause severe burns.

Instruction

Brief Instruction

General Description

INVCHR2 and INVCHR3 are 2-in-1 inverter chargers designed for high power management applications such as RV, utility vehicles, marine and emergency.
With the rapid charging capability of Projecta’s lithium batteries, the Inverter Chargers can provide high current charging from a mains source and are capable of starting and powering the most demanding appliances, such as air conditioning, water pumps, washing machine, freezer, compressor, power tools and induction cooktops.

Inverter Charger Functions

Grid Boost is a useful feature when limited grid supply is available or working with a generator. The Inverter Charger will disconnect the mains AC power providing power from the inverter and battery or boost this power using AC mains and the inverter / battery power. With this feature, you can avoid tripping a shore power circuit breaker or reduce generator capacity by up to 50%.

Powerful and Reliable Inverter

High performance pure sine wave

INVCHR2 and INVCHR3 are pure sine wave inverters generating a near perfect waveform.

High surge power capability

Providing outstanding surge power capabilities you can easily run heavy inductive loads like fridges, coffee makers, microwaves, power tools, air conditioning and induction cooktops.

Battery low voltage protect

Inverter Charger provides configurable battery low voltage protection.

Professional Battery Charger for lead acid battery

Multi stage sophisticated charging algorithm for lead acid battery

Fitted with multistage charging algorithm (bulk-absorption-float-recycle), the built-in charger of Inverter Charger is designed to charge the battery quickly. Microprocessor controlled charging algorithm with variable absorption charging timer will guarantee optimal charging for batteries of different discharged state.

PROJECTA-INVCHR2-Intelli-Grid-12v-Inverter-Charger-

Float charging and recycle charging program guarantee your battery is getting proper maintenance in case of long standby periods providing less aging.

Battery Sample Cable (Temperature and voltage)

Battery temperature is a key factor in correct charging for lead acid batteries. The charging formula must be adjusted (automatically and in real time) according to the actual battery temperature to ensure that the battery is fully charged but not overcharged or undercharged. All charging voltages recommended by battery manufacture are in fact ONLY applied at 20°C-25°C and the temperature probe ensures optimal charging..

The Bat sample cable (battery temperature and voltage sensor) supplied with Inverter Charger measures the temperature of battery and automatically makes adjustments at real time to properly charge your batteries at compensation rate of – 4mV/°C/cell. In case of Bat sample cable is not present, Inverter Charger will use 25°C as default setting. This feature is especially recommended for sealed batteries and/or when important fluctuations of battery temperature are expected.

Different battery chemistries

Inverter Charger offers premium charging algorithm for commonly encountered lead acid battery chemicals include AGM, GEL, Wet, lead-carbon and Lithium battery, of which you can set through the LCD/LED interface.

Lithium Battery Compatible

Projecta Inverter Chargers support universal LFP charging profile and offered pre-defined LFP charging profile for Projecta HD series lithium batteries.

Built in BMS pre-defined LFP charging and communication for LBXXX-HD series batteries

According to cell temperature and real time SOC, BMS will send commands to battery charger asking for optimum charging voltage and current. This synchronization will prevent overheating or overcharging especially at the end of charging, to extend the life of the battery.
Instead of using voltage as protection, SOC value is used to avoid permanently damaging of lithium batteries due to being left discharged for long time.

AC Transfer Switch

In case of poor AC mains power (due to poor voltage/ frequency or waveform characteristic, the Inverter Charger will switch to inverter and battery power. In case of AC mains failure or exceeding the maximum AC input current set by the user, the Inverter Charger will initiate a quick switch to inverter, which will guarantee continuous power. When stable AC power is resumed, the inverter charger will switch back to AC mains power after a 5 second delay. Due to its ultra quick transfer design, as quick as 0ms. The Inverter Charger could be used as a UPS.

Ground Relay

PROJECTA-INVCHR2-Intelli-Grid-12v-Inverter-Charger-
fig-7

The neutral output of Inverter Charger is automatically connected to earth upon no external AC sources are available. Once external AC sources present, the ground relay will open. The Ground relay is required for the RCD to function correctly.

Protections and Safeguards

The Inverter Charger is equipped with a series of complete hardware and software protection functions to ensure its stable and reliable operation.

Overload protection

When overload protection is trigger on, it will restart automatically after 60s. And after three consecutive overload shutdown protections, the equipment will not restart automatically. At this time, the user needs to manually restart.

Over temperature protection

When the internal temperature is too high, Inverter Charger will enter into the over-temperature protection. After the internal temperature returns to normal, it can automatically resume normal operation.

Short circuit protection

The equipment will automatically shut down when the AC output is shorted and needs to be manually activated.

Battery over temperature protection

During charging, the equipment will continuously monitor the battery temperature. When the battery temperature is too high, the equipment will automatically reduce the charging current.
When the battery is hot the charger will automatically turn off to protect the battery.

Battery low voltage protection

To prevent the permanent damage caused by the over discharge of battery, the equipment will automatically cut off the output according to the low voltage protection point set by the user.

RCD (RCBO)

The Inverter Charger is fitted with an RCD (Safety Switch) to ensure maximum protection for our customers.
The RCD is also fitted with an over current feature to protect wiring. If the RCD trips it will need to be manually reset.
