I wouldn t add a second charge controller unless it s the same as the present one so as to minimize problems between them.
Adding a second solar panel to rv.
Many rvs come prepped for the addition of solar panels.
No costly fuel required.
For larger solar panel arrays you will need either 4 mmsq or 6 mmsq cables.
Add a second solar pv system along with batteries if your existing inverter is still relatively new e g.
It should be written on the wire.
If you can find panels that match the existing panels i d only look at adding 2 more and replacing the pwm with an mppt controller.
This way the camper will always be ready to go and the dedicated solar panels will also keep the camper s existing deep cycle battery topped off when not in use.
Best for your batteries.
For systems up to 200 watts total solar panel wattage a wire size of 2 5 mmsq 14 awg is adequate as long as the total cable length from the solar panel to the battery is less than 8 metres.
No noise unlike generators or wind turbines.
Less than 5 years old it might make sense for you to add a brand new solar system in parallel with your existing one.
Check the wire size.
Free energy from the sun is transformed into pure dc electricity.
This may also prevent the screws from.
But i recommend adding a second coat of flex seal over the entire bracket as good measure.
Whiel most of these models are newer even older rvs can be outfitted with solar panels pretty easily.
That panel is rated at 100 watts at peak efficiency meaning on a 78 degree cloudless day at solar noon on the equator during the equinox.
No risk of carbon monoxide poisoning or fires as with.
In some of the newer instances that use this form of wiring the charge controller is already present the only piece that needs to be added is the solar panels themselves.
Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs.
It s greater efficiency will offset the smaller array.
Top 10 reason to go solar.
This second system could include a hybrid inverter which manages both the new solar plus the batteries but in this.
This prewired for solar rv included the installed charge controller but it did not have any solar panels installed from the factory.
