JNPES-3KL-5120 Residential Kit with 3 kW Inverter

JNPES-3KL-5120 Reference Configuration

The JNPES-3KL-5120 is a residential configuration combining a PV array, an inverter, and a battery. The ratings are stated separately: the two panels total 1.16 kWp, the JNF3KLF-X-V1 inverter has a published rating of 3 kW and the JNB051100-W battery has a nominal energy rating of 5.12 kWh. Therefore, “3 kW” refers to the inverter, not the PV-array capacity.

Kit reference: JNPES-3KL-5120 · PV: 2 × 580 Wp = 1,160 Wp · Inverter: JNF3KLF-X-V1, 3 kW, 48 V battery system · Battery: JNB051100-W, LiFePO4, 5.12 kWh nominal · Last updated: August 19, 2026.

Kit Bill of Materials

Element	Reference or Published Value	Quantity
Photovoltaic Panel	580 Wp per panel	2 panels, 1.16 kWp total
Inverter	JNF3KLF-X-V1, published 3 kW rating, 48 V battery system	1 unit
Storage Battery	JNB051100-W, LiFePO4, 5.12 kWh nominal energy	1 unit
Mounting Structure	Metal structure to be adapted for roof or ground mounting	1 set
Cables and Accessories	Contents and cable lengths defined after the site survey	1 configured set

This bill of materials describes the kit baseline. The final quotation must state the exact panel model, mounting structure, cable lengths and cross-sections, connectors, enclosures, isolation devices, surge protection, earthing, and distribution-board modifications. These items vary by building and are not implicitly included by the phrase “cables and accessories.”

Understanding the Three Ratings

• 1.16 kWp PV array is the combined nameplate peak rating of the two panels under reference conditions. Daily production depends on location, orientation, tilt, shade, temperature, and system losses.
• 3 kW inverter rating is the published rating for the JNF3KLF-X-V1. It does not mean that every 3 kW load can start at the same time: simultaneous loads, motors, compressors, and their starting surges must be listed.
• 5.12 kWh battery is a nominal energy rating. Usable energy is lower and depends on the permitted depth of discharge, efficiency, power demand, temperature, state of charge, and ageing.

The relationship between these ratings matters. A 5.12 kWh battery can support a 500 W average load for several hours, but exact runtime cannot be calculated without usable energy and system losses. Likewise, a 3 kW inverter does not turn a 1.16 kWp PV array into 3 kW of solar generation. This combination may accommodate load peaks or future expansion, subject to the model’s electrical limits.

Grid, Battery, and Backup Operation

Operation during a grid outage depends on the wiring and the mode actually configured. The quotation must distinguish the grid input, any backup output, priority circuits, power available in battery mode, charging strategy, and transition between sources. A battery does not mean that the whole home automatically remains powered without interruption.

Before installation, WOW2000 works with the customer to list the loads that must remain powered, such as lighting, refrigeration, television, ventilation, IT equipment, pumps, or other appliances. High-power equipment may remain on the main grid supply or require a larger system. Any grid connection must include protection, earthing, and settings appropriate for the local installation.

Information Required for Sizing

• city and building type, with photos of the roof or ground area;
• electricity bill or estimated daily consumption in kWh;
• list of loads, power ratings, operating times, and motor-driven equipment;
• typical outage duration and required backup time;
• single-phase or three-phase installation, grid voltage, and existing distribution board;
• distance between the panels, inverter, battery, and distribution board;
• existing equipment and potential future expansion.

This information determines whether the reference configuration is suitable or whether the panel count, storage, inverter, protection, or priority-circuit architecture must change.

Installation, Commissioning, and Limits

A complete installation normally includes the site survey, location approval, mounting, wiring, protection, configuration, testing, and an explanation of system operation. The exact scope depends on the quotation. Roofing or masonry work, major distribution-board modifications, long cable runs, transport outside the agreed area, and special procedures are not automatically included.

The customer should receive the final bill of materials, installed references, essential settings, shutdown and restart instructions, and warranty terms applicable to each component. Backup time, generation, and savings depend on the actual usage profile and are not fixed values for every home.

Estimated Price in Gabon

2,500,000 to 4,500,000 XAF for a study and configuration based on this reference, depending on the critical loads to be supplied, selected storage, protection, mounting structure, cable lengths, installation, and destination. This range does not represent two stocked products and is not a firm offer.

The written quotation states the BOM version, quantities, inclusions and exclusions, tax status, transport, work scope, schedule, payment terms, and validity period. Any change to the PV capacity, battery, or installation changes the final amount.
