Off-grid capability isn't a single part but a balanced system of power, water and waste. We calculate your needs, check what the manufacturer sensibly offers ex works – and build the rest in-house, including cabinetry changes from our own joinery.
Our services
Batteries
Lithium leisure batteries from 100 to 600 Ah with DC-DC charger, solar and battery monitor. We use the original bays or fabricate new mounts in our metal shop.
LiFePO4 with heating for winter trips
30–60 A DC-DC chargers
100–400 Wp flush-bonded solar
App monitoring
Inverters
Pure sine wave from 1,000 to 3,000 W, optionally with automatic transfer switch so every socket works without shore power.
Coffee machine, hairdryer, induction
Automatic transfer switch
VDE-compliant fusing
Quiet mounting away from the bed
Fuel cells
EFOY fuel cells charge the battery quietly regardless of weather – ideal for winter trips and long stays without sun.
EFOY 80 / 150
Cartridge bay with exterior access
Automatic charge start
Works alongside solar
Composting toilets
Odour-free, chemical-free and weeks without a dump station. We fit composting toilets into the existing bathroom and adapt cabinetry and ventilation in our joinery.
Conversion from cassette toilet
Active exterior ventilation
Made-to-measure panels
Reversible to original
Upgraded and converted as a whole
From manufacturer to workshop: we can do almost everything ourselves.
Togo Reisemobile used to be a manufacturer. That experience now lives in over 1,200 m² of workshop space – with our own joinery, upholstery, metal shop and 3D printing for precise templates. We work with original manufacturer parts and materials so conversions look factory-made.
Our rule: where it makes sense, we rely on the manufacturer's factory options. For special cases, retrofits and used vehicles we do almost everything in-house.
We calculate that together based on your consumers. Often 200 to 300 Ah of lithium with solar is enough – if you use induction cooking, air conditioning or power tools you need more capacity and a stronger inverter.
Does the manufacturer warranty remain after a retrofit?
Yes. We use original manufacturer parts, document every installation and observe the specified cable cross-sections and fuses. Where the manufacturer offers a factory pack, we recommend it for new orders.
Is a fuel cell worth it compared with more solar?
Solar is unbeatably cheap in summer but delivers little in winter or in the shade. An EFOY fuel cell recharges regardless of the weather and makes sense if you want to stay off-grid in winter or for weeks. We often combine both.
How does a composting toilet work day to day?
Solids and urine are collected separately: no chemicals, hardly any odour, longer intervals between emptying and disposal via household waste or a toilet. We fit it to measure in place of the cassette toilet – with active exterior ventilation and the option to revert.
Can I run a coffee machine and induction hob from an inverter?
Yes, with the right design. We size the inverter, battery and cable cross-sections for your appliances and set up priority switching and shore-power changeover so nothing gets overloaded.
How long does an off-grid package take?
A typical package of lithium battery, DC-DC charger, solar and inverter takes two to three working days. With additional cabinetry work or a composting toilet we allow more time – appointments are confirmed with you in advance.
