I’m looking to put approx 350 watt of panels on the roof to a hymer 704. Probably in 3 panels. The m/h has an ELB 29 with 2 x 95ah leisure batteries.
1 where is the best place to source panels. Is it true that the more cells they have, the better quality?
2. the max length of cable between panel and ELB is approx 7 m. The rest shorter depending where I put the panels. What size cables ?. Also is it better to join the cables on the roof in a busbar and then a single cable to the ELB (cable size?)or 3 cables to the ELB assuming they are arranged in series.
3. I want to charge leisure and vehicle battery. Do I use the Schaudt LMR1218 controller or is there a better option. The vehicle control panel doesn’t have ability to show Solar charge - should I use something else that is compatible with the chosen controller assuming it’s not a Schaudt.
4. I’m hoping to put the controller about 1m from the batteries. What size cable.
sorry from so many questions but there seems endless choice.
There seems to be many options for fixing to the roof. Metal brackets seem to be the better choice and many saying the mastic is good enough. The roof is protected with fibre glass - does that make a difference . I don’t want to screw down if can be avoided.
