JNAT-0464A20-10 Kit Overview<\/h2>\n\n\n\n

The JNAT-0464A20-10<\/strong> is a portable solar lighting kit consisting of a PV panel, a power unit with an LFP battery, and three wired LED lamps. To avoid ambiguity, this page identifies the product by model and states each power rating separately: 18 W for the panel<\/strong>, 5 W per lamp<\/strong> and 15 W for all three lamps operating together<\/strong>. The \u201c20 W\u201d wording retained in the historical URL must not be interpreted as the panel rating or the total lamp load.<\/p>\n\n\n\n

This page uses the term polycrystalline<\/strong> for the panel and LiFePO4<\/strong> for the battery. It does not retain the former \u201c23% monocrystalline panel\u201d or \u201c18650 cells\u201d wording, which described components that differ from those listed in the table.<\/p>\n\n\n\n

Runtime Calculations<\/h2>\n\n\n\n

The nominal battery energy is calculated as follows: 3.2 V \u00d7 18 Ah = 57.6 Wh<\/strong>. The durations below are theoretical limits obtained by dividing nominal energy by the load. They do not deduct converter and wiring losses, reserve capacity, temperature effects, ageing, or consumption by the radio or ports.<\/p>\n\n\n\n

Lighting Mode<\/th>Rated Load<\/th>Theoretical Maximum Runtime<\/th><\/tr>
Three Lamps On<\/td>15 W<\/td>57.6 Wh \u00f7 15 W = 3.84 h<\/td><\/tr>
Two Lamps On<\/td>10 W<\/td>57.6 Wh \u00f7 10 W = 5.76 h<\/td><\/tr>
One Lamp On<\/td>5 W<\/td>57.6 Wh \u00f7 5 W = 11.52 h<\/td><\/tr>
Average Load for 24 Theoretical Hours<\/td>2.4 W<\/td>57.6 Wh \u00f7 2.4 W = 24 h<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Actual runtime is therefore lower than these theoretical values. Any 10-to-24-hour statement must specify the number of lamps, their power level, simultaneous use of the radio or ports, initial state of charge, and battery cutoff voltage.<\/p>\n\n\n\n

Solar Charging<\/h2>\n\n\n\n

With an 18 W panel, 57.6 Wh \u00f7 18 W gives a theoretical minimum of 3.2 full-power hours before any loss. In practice, panel output varies with irradiance, clouds, temperature, orientation, shade, battery state, and controller efficiency. The stated 6-to-8-hour charging time is therefore indicative under favourable exposure, not a daily guarantee.<\/p>\n\n\n\n
