These are used to fasten the profile rails, which form the basis for the PV module structure, using carriage bolts or special profile screws of a suitable length.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rubber seals and body washers should be used to dampen vibrations. The assembly sequence is then as follows: Place the rubber seal on the hole suitable for the screws, then place a body washer on top. This applies to all holes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The screws are then inserted into the groove of the mounting profiles and placed on the roof together with the profile so that they are congruent with the drill holes, fine-tuned and then slowly tilted towards the drill holes, corrected again if necessary and then lowered fully into the drill holes until they rest on the body panels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A rubber seal is now screwed on from the inside, followed by the body washer and self-locking nut, and tightened with feeling. The rubber seal should not deform in the process!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Using purchased or self-made aluminum brackets, the transverse and subsequent longitudinal profiles are screwed on, to which the PV modules are attached using the brackets provided. All nuts should be fitted with a toothed flange.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If roof hatches are installed under the PV modules, the distance from the rear of the module must be dimensioned so that the roof hatches can be fully opened. This may well be a distance greater than 10 cm. The mounting profiles used must be dimensioned accordingly. The longitudinal profiles should be as high as possible and the crossbars as low as possible in order to keep wind resistance as low as possible. The longitudinal profiles mounted on them accommodate the mounting brackets of the PV modules.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The crossbars must not be attached above the roof hatches, but only in front of or behind them to ensure unhindered opening and closing of the hatches.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/IMG_3735-1024x768.jpg\" alt=\"\" class=\"wp-image-9964\" srcset=\"https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/IMG_3735-1024x768.jpg 1024w, https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/IMG_3735-300x225.jpg 300w, https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/IMG_3735-768x576.jpg 768w, https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/IMG_3735-1536x1152.jpg 1536w, https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/IMG_3735-2048x1536.jpg 2048w, https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/IMG_3735-16x12.jpg 16w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Anordnung_Cerbo_GX_Display\"><\/span>Cerbo GX display arrangement<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Victron Cerbo GX Touch 70 display found its place here above the small storage compartment above the rear-view mirror (including a digital clock, NTP via router) and attached to the rear-view mirror, a tablet for navigation and as a monitor for the reversing camera.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"915\" height=\"1024\" src=\"https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/image-5-915x1024.png\" alt=\"\" class=\"wp-image-7869\" srcset=\"https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/image-5-915x1024.png 915w, https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/image-5-1373x1536.png 1373w, https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/image-5-1831x2048.png 1831w, https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/image-5-11x12.png 11w, https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/image-5-268x300.png 268w, https:\/\/csiag.eu\/wp-content\/uploads\/2024\/10\/image-5-768x859.png 768w\" sizes=\"(max-width: 915px) 100vw, 915px\" \/><figcaption class=\"wp-element-caption\">Victron Cerbo GX Touch 70 at a glance<\/figcaption><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fazit\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Previous \"worst case\" was a 6 percent discharge of the LiFePo4 batteries to 94 %, which were usually balanced out again in the course of the morning (without charging boosters \/ driving), purely through PV energy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this respect, 100 percent self-sufficiency can be assumed.<\/p>","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading time<\/span> <span class=\"rt-time\"> 4<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>The MB Sprinter as a self-sufficient extension - a justified wish for motorhome owners.
