Panel works well in UK mid March sunshine producing more than the specified output. And the EcoFlow delta 2 does everything the reviews on YouTube tell you about it, so hopefully this set up will keep our caravan leisure battery topped up as you can see in the photos with it plugged straight into the caravan system charging the onboard battery and other electrics. Main advantage is none of the caravan electrics are altered which may affect insurance or resale value as this is a costly option if installed professionally going solar this way is a stand alone unit which can be used elsewhere.
