Emergency Lighting

[Pete Grey]

Both MB and BP bring up valid points, you do not need 24/7 power for lighting, just a few hours of an evening.

If your batteries are not identical they will not charge evenly, and you will need a powerful charger, at least 20amp.

If you’re running a lamp which draws 1amp for 6 hours (say 4pm-10pm of a winter evening) and your solar panel (100w) only gives you 1.5amps for 4 hours (10am-2pm lightest part of the day) you’re maintaining the status quo any more power for charging your phone etc is a bonus.

Our new system is two 120w panels charging two identical leisure batteries through a 30amp charge controller. At the moment plenty power for our needs.

The 100w folding panel (bought for the camper) charging one leisure battery is backup.
