JK SOC DISPLAY 4.3 INCH V19

JK V19 4.3-Inch Battery SOC Display

The JK V19 4.3-Inch Battery SOC Display is the version-specific display option for a matched JK-PB V19 inverter BMS. It should be selected by the required hardware generation, not simply as any JK 4.3-inch screen.

A local display is useful in an energy-storage installation where the user needs an equipment-side battery interface. The V19 designation helps procurement and service teams keep the intended screen separate from older or differently connected display families with the same nominal diagonal.

Technical Performance & Engineering Details

The referenced V19 display family is identified as LCD-4.3-TTL-P for JK-PB inverter-BMS equipment. The central engineering requirement is the approved screen-to-board pairing. A display that receives the correct information from one management-board generation is not automatically compatible with another generation.

The screen presents battery information; the BMS performs the underlying measurement, charge estimation and protection. A display menu relating to inverter protocols should not be confused with permission to wire the screen to any inverter communication port. The physical display connection and the BMS-to-inverter communication arrangement must be identified separately.

Record the complete JK-PB model and V19 revision before ordering. Match the display's full model label, cable and documented supply arrangement to that board. Keep this V19 item distinct from the separately listed JK 4.3-inch display without a version suffix.

For a cabinet containing more than one battery, establish which unit the screen is intended to represent and which data views are supported by the approved configuration. Do not assume that the presence of a display alone creates parallel-pack communication. Check the panel drawing, rear clearance and service access, and specify the required operator permissions before commissioning the system.

Applications

• Matched JK-PB V19 inverter-BMS installations.

• Battery cabinets requiring a version-specific 4.3-inch interface.

• Like-for-like replacement of an approved V19 display.

• Local SOC checks during energy-storage commissioning.

• Maintenance identification of screen and BMS revision pairs.

Installation Guide

Complete screen mounting and wiring with the battery safely isolated. Follow the exact V19 display and BMS documentation for the harness; do not reuse an older cable without approval. Check the display supply requirement separately from the battery's nominal or fully charged voltage.

After startup, verify that the screen communicates with the intended board and that its charge indication agrees with the BMS. Test only the functions enabled in the approved configuration. Restrict any settings that affect battery or inverter operation to authorised personnel, and preserve the commissioned parameters. Record the board revision, screen label and harness so that later replacement parts can be selected without relying on the 4.3-inch size alone. Record the V19 designation explicitly in the spare-parts list for future maintenance and replacement orders.

Why Choose ARB Accessories?

ARB Accessories offers JK monitoring accessories alongside battery-management and pack-assembly components for Indian buyers. Provide the complete BMS model and revision, the display label and the intended mounting arrangement when enquiring. Matching these details at the purchasing stage helps distinguish similar-looking screens and keeps replacement parts consistent with the equipment already in use.
