This bundle consists of 4 × SolarFam Mono 100Wp Black solar panels, together providing 400Wp of solar power. This is an interesting set for self-built campers where you want to make the most of the roof space with narrow, black glass panels.

The panels have a black aluminium frame, tempered glass, MC4 connection cables and an IP67 junction box. This makes this bundle suitable for a neat, fixed solar panel installation on a camper roof.

Why this 400Wp SolarFam bundle? ▾
  • 400Wp total power: made up of 4 identical SolarFam Mono 100Wp Black solar panels.
  • Narrow size per panel: 1190 × 450 mm, useful for camper roofs with limited or fragmented roof space.
  • Bundle discount: more affordable than purchasing the same panels separately.
  • Black version: black frame and dark cell construction for a sleek look on the roof.
  • Plenty of solar power for campers with refrigerators, ventilation, laptop use and frequent off-grid camping.
  • MC4 connection: standard solar panel connectors, easy to combine with solar cables and MPPT controllers.
Actual yield is highly dependent on season, sun exposure, shade, panel orientation and the state of charge of your battery. In winter or with shade, the yield is significantly lower than on a sunny summer day.

Tip: always measure your camper roof carefully beforehand. Take into account roof hatches, fans, roof rails, shadows from accessories and the location of the cable entry. Also measure the space required for the mounting material. Roof supports or spoilers often protrude slightly beyond the panel, and the required space depends on the chosen mounting method.

How to connect 4 panels? ▾

With four solar panels, the connection method is extra important. We generally do not recommend connecting all four panels fully in series with this bundle, as the voltage can become too high for the recommended charge controllers. Connecting all panels in parallel is still possible in some situations, but then a relatively large current flows through the solar cables.

Most logical: series-parallel, also known as 2S2P
The most logical setup is usually series-parallel connection. You create two groups of two panels in series. These two series groups are then connected in parallel with each other.

  • Group 1: panel 1 and 2 in series.
  • Group 2: panel 3 and 4 in series.
  • Then connect both series groups in parallel with MC4 parallel connectors 2-in-1.
  • You then need one solar cable set for the cables leading indoors, towards the MPPT charge controller.

Connecting all panels in parallel
Connecting four panels in parallel can sometimes also be an option, for example, if you expect a lot of uneven shade. For this, you use MC4 parallel connectors 4-in-1. Keep in mind that the current through the solar cables will then be higher. The correct cable diameter (6mm2 instead of 4mm2) and cable length then become more important.

Are the panels far apart or do you want to connect them in parallel due to shade? Then accurately measure how much cable length you need on the roof. Let us know this length by mail or WhatsApp, and we can make a custom solar extension cable set for easy and neat installation.
Which charge controller and battery cables do you need? ▾

For this bundle of 4 × 100Wp, we usually recommend the Victron SmartSolar MPPT 100/30 for a 12V battery installation. This charge controller is well suited for 400Wp solar power on a 12V camper installation, especially when you connect the panels in series-parallel.

Are you using a 24V battery installation?
Then this bundle can also be used with an appropriate circuit. For a compact 24V installation, the Victron SmartSolar MPPT 75/15 is sufficient.

Note: always check whether the maximum input voltage and input current of the MPPT match the chosen circuit, especially at low outdoor temperatures. Feel free to send us your plans, and we will help you determine the appropriate controller and circuit.
Connecting MPPT to battery ▾

With 400Wp of solar power, more current flows on the battery side of the charge controller than with smaller solar panel sets. Therefore, for a 12V installation, you should not use a light standard battery cable set, but individual battery cable with appropriate cable lugs and a MIDI fuse close to the battery.

  • Short distance up to approx. 1 meter: use 10mm² battery cable.
  • Longer distance between MPPT and battery: use 16mm² battery cable.
  • Place a MIDI fuse 40A in a MIDI fuse holder.
  • Place the fuse holder preferably within 15 cm of the positive terminal or positive connection at the battery.
  • Use appropriate crimp cable lugs on the battery cable.
  • For the MIDI fuse holder, you need 2 × M5 cable lugs.
  • For connection to the battery, M8 is usually needed, but this can also be M6 or another size, depending on your installation.
To mount crimp cable lugs on battery cable, a good professional cable lug crimping tool is required. You can order this tool and possibly return it after use. Would you rather not do this yourself? We can also custom-make the battery cables for you with the correct cable lugs. For this, we charge the necessary workshop time based on our current hourly rate.
Other SolarFam 100Wp bundles ▾

Do you want less solar power or does 400Wp not fit on your roof? This SolarFam 100Wp panel is available as a single panel and as a bundle with multiple panels. A bundle discount applies when purchasing multiple panels at once.

What is this bundle suitable for? ▾

This 400Wp bundle is suitable for permanent mounting on campers and van conversions where you want to build up a lot of solar power with four narrow glass panels.

  • A robust solar panel base for campers that are regularly off-grid.
  • Suitable as a charging source for installations with a compressor refrigerator, LED lighting, water pump, fan, laptop use, and other daily consumers.
  • Charging a 12V or 24V battery bank via a suitable MPPT charge controller.
  • Expansion of an existing camper installation with additional solar power.
  • Flexible roof layout due to four narrow panels instead of one or two large panels.
  • Suitable as part of a complete off-grid system with battery, MPPT, alternator charger, and/or shore power charger.
400Wp is a lot for a camper roof, but it remains dependent on sun, season, and shade. For winter use or high power consumption, charging via alternator or shore power remains important.
Mounting on camper roof ▾

These panels are usually mounted with aluminium roof brackets or spoilers. Ensure strong mechanical mounting, good sealing and a neat cable route to the interior.

With four panels, pay extra attention to shade and roof layout. A roof hatch, fan, roof rack or roof box can noticeably reduce the yield of one or more panels. This can also influence the choice between series-parallel or fully parallel connection.
What else do you usually need? ▾
  • Battery cable 10mm² or 16mm², depending on cable length and installation
  • MIDI fuse 40A + MIDI fuse holder
  • Crimp cable lugs suitable for fuse holder, MPPT, and battery connection

    Common mistakes ▾
    • Connecting four panels fully in series to an MPPT that is not suitable for the maximum input voltage.
    • Connecting four panels fully in parallel without considering the higher current through the solar cables.
    • Using an MPPT that is too small or unsuitable for 400Wp solar power.
    • Using too light a battery cable between the MPPT and the battery.
    • Not placing a fuse close to the battery on the positive side of the MPPT connection.
    • Using the wrong size cable lugs for the fuse holder or battery connection.
    • Combining panels with different voltages or powers without checking the specifications.
    • Leaving cables loose on the roof, with risk of chafing, leakage, or cable breakage.
    • Insufficiently sealing the roof penetration or using the wrong sealant/primer for the roof material.
    FAQ ▾

    Why four smaller 100Wp panels instead of one large solar panel?
    One large solar panel is often cheaper per watt, but on a camper roof, that is not always the best choice. With four smaller panels, you are much more flexible in arranging your roof, for example around roof hatches, fans, rails, or other obstacles. In addition, smaller panels, due to their shorter and narrower frames, are usually stiffer than large household panels. Our experience, and that of several camper builders, is that smaller solar panels on campers often last longer in practice and pose less risk than large panels with a long and wide frame. Especially on a vehicle, where you are dealing with driving wind, vibrations, temperature fluctuations, and movement of the roof, this is an important advantage.

    Can I connect all four 100Wp panels in series?
    We generally do not recommend this for this bundle, as the voltage can become too high for the recommended charge controllers. Usually, series-parallel connection is more logical.

    What is the most logical connection for four panels?
    Usually 2S2P: two panels in series, another two panels in series, and these two series groups in parallel with each other. For this, you use MC4 parallel connectors 2-in-1.

    Can I connect all four panels in parallel?
    This is sometimes possible, for example, with a lot of uneven shading. In that case, use MC4 parallel connectors 4-in-1. Be extra mindful of the higher current through the cables.

    Which MPPT charge controller do you recommend for 12V?
    For this bundle, we recommend the Victron SmartSolar MPPT 100/30.

    Which battery cable do I use between the MPPT and the battery?
    For a short distance of up to approximately 1 meter, use a 10mm² battery cable. If the charge controller is further from the battery, 16mm² is often more sensible. Also, place a 40A MIDI fuse with a fuse holder close to the battery.

    Can you custom-make the battery cables?
    Yes, we can. We can custom-make the battery cables with suitable cable lugs for you, so you can connect them neatly right away. For this, we charge the necessary workshop time based on our current hourly rate. For a simple cable set, this usually remains limited. You can also make the cables yourself with a suitable crimping tool for cable lugs.

    Is 400Wp enough for my camper?
    That depends on your consumption and travel habits. 400Wp is a solid base for many camper installations, but with high consumption, winter use, or multiple days of off-grid camping, battery capacity and charging via alternator or shore power also remain important.
