## Overview

This 15W Off-Grid Solar Lighting System is a turnkey solution for illuminating spaces without mains electricity. Featuring a 15W solar panel, a 7Ah 12V battery with built-in charge controller, and four 3W LED lights, it delivers 5-6 hours of bright, reliable lighting after a full day of sun. The system includes long cables with switches and a USB port for charging mobile devices, making it perfect for sheds, barns, camping, or any remote location. Easy to install and maintain, it offers sustainable, eco-friendly power with no wiring or electrician needed.

## Description

This solar lighting system is ideal for places with no mains electricity such as outhouses, sheds, garages, farms, stables, as well as for camping, travel and any outdoor activities (e.g. for a yurt). The system is fully independent from the grid / AC power source and works purely based on sunlight energy. During the daytime, the 15W solar panel charges a 12V battery inside the control unit, which then provides power to the 4 x 3W 12V LED lights connected via front sockets on the control unit. In addition, there is a standard 5V USB socket for charging mobile phones and USB compatible devices. The control unit has a built-in 7Ah battery with an automatic solar charge controller to manage the charging process and prevent overcharging. The 15W solar panel supplied with the system can fully charge this battery within about 7-8 hours of bright sunshine (longer in cloudy weather), and the battery can provide enough energy to power 4 LED lights continuously for 5-6 hours, or twice as long if only two LED lights are connected. The system is very convenient to use and install: the solar panel comes with a 10m cable (would suit most objects, as longer distance is rarely required), and each LED light comes with a 5m cable with an On/Off switch. All cables come with connectors for a quick "plug and play" installation. System specifications: - System voltage: 12V - Battery capacity: 7Ah - LED lights power: 3W - Length of solar panel cable: 10m - Length of LED lights cables: 5m - USB output current: 0.6-0.8A - Max DC output current: 2A - Control unit case size: 220 x100 x 170 mm - Solar panel size: 265 x 410 x 20 mm - Control unit case weight: 3.44 kg - Solar panel weight: 1.7 kg Please contact Photonic Universe if you have any questions about this product.

## Questions & Answers

**Q: Is there an option to mains charge the battery, say on initial use or in very cloudy weather?**
A: As the battery is a 7Ah capacity, safe charge would be at 10% of that which is 0.7Ah. If you buy a trickle charger that as an output rated no higher than 0.7Ah (700mAh) and the battery is carefully measured with a multi meter every so often as to not overcharge, the battery can be safely charged by mains power. However, the cover from the box would need to be opened and this may invalidate a manufacturers warranty. Please charge with care and disconnect battery from wiring harness in box when battery is charging.

**Q: When the unit is set up with the solar panel attached, for charging the battery, does the "master switch need to be "on" or "off?"**
A: just to point out that the unit will not charge the internal 12v battery if the power switch is off. The unit has a regulated charging system that will not "overcharge" the battery. However, as per the instructions given, if the battery is allowed to discharge completely the unit will have to be looked at by an electrician. The moral to this story is "do not switch off the main power switch".

**Q: I know it might not be practical, but is there a way to use an ac (3 pin) plug with this product? is there an adapter i could purchase?**
A: If by 3 pin plug you mean to attempt to run a 240v item from this piece of kit, it doesn't work like that. Output is only low voltage. If you are asking can you charge this piece of kit, I believe it may be possible but would suggest you contact the manufacturer. Great piece of kit though.

**Q: Can you carry this on a commercial flight?**
A: Hello,

Thank you for your interest in our 15W solar lighting system and taking this on a flight.

Probably not, as it is quite big and has a 7Ah lead acid battery inside. Please check with the company you are flying with to see if they accept a solar panel and a battery as the restrictions may vary. 

Kind regards,
