Bailey solar charging problem

If it’s just the standard Bailey panel I doubt it is large enough. As our MH is kept in storage and I need to power an alarm and tracker for insurance purposes I had two x 90 watt panels fitted. Through the 3 winters we have owned it we have had no problems keeping both habitation and cab batteries charged. Our MH is stored in an open location and there are no obstructions such as trees, houses etc, all of which will affect efficiency. Although I didn’t buy them with the intention, the panels have the additional benefit that we can use them on off grid Aires in France.

 

The van is set up with a 100w factory fitted panel and a Truma SDC20 smart charger and ive had no previous problems over the last 8 winters.

I have a Valencia 3, during Covid i started to plug my Nissan Navara into the spare terminals on the charge controller as its battery kept dropping its voltage due to lack of use. Both batteries were kept fully charged by the single solar panel.

I had the same controller on my 2016 Vigo S3. Last year the controller died and killed my Banner 110aH battery (charged it at 15+v and gassed away the electrolyte). 

I replaced the controller with one from ebay with an adjustable float voltage and added a lithium battery with a smart BMS, bluetooth monitor and charge protection. The solar panel is  fine, and my battery has stayed well charged all winter.

Check that the Solar regulator is working correctly just had similar problem with my panerl and battery ended up that I needed new regulator all working well now. However over the winter if battery remains connected it will need a boost direct from mains power system
