The abbreviation HV stands for "high voltage".
72 cells instead of the usual 36 cells promise yields even under unfavorable light conditions, so that MPPT charge controllers can work optimally here with their maximum power point technology. In unfavorable diffuse light conditions, conventional solar modules only deliver a low voltage that is no longer sufficient to charge the battery. By increasing the number of cells and the associated increase in voltage, it is ensured that the voltage is sufficient to catch the last rays of the sun even in times of the year when there is little light.
Another advantage: With the same performance, an increase in voltage results in a reduction in the current load on the cables. Due to the high operating voltage, cable losses are reduced and smaller cable cross-sections can be used.
Light, innovative and flexible
Thanks to its innovative design, the WATTSTUNDE® SunFolder solar bag is extremely light and absolutely space-saving and thus offers a high degree of flexibility and user-friendliness. The solar bag can be adjusted freely at any time. Whether behind the windshield when parking or outdoors, you can place the solar bag anywhere the sun shines. You can also guarantee a high energy yield with SunPower rear-contact solar cells.
SunFolder+ novelty: bypass diodes
The main novelty: built-in bypass diodes. As a result, the yield is even better, since partial shading no longer inhibits the performance of the SunFolder as much. So the SunFolder+ solar panel does not have to be moved immediately if the shadow of a branch covers part of the solar cells.
Robust and flexible
The robust Cordura fabric makes the SunFolder the perfect companion for outdoor use - however, as with any technical device, care should be taken to ensure that no moisture or water penetrates sensitive areas. We recommend not leaving the SunFolder outside overnight. (It's an electronic device that uses solar energy—that is, it doesn't tolerate mist or rain.)
Plug & Play thanks to the practical plug-in system
The solar pack SunFolder from WATTSTUNDE® has a 5m long connection cable with an Anderson connector system at the end. Thanks to the practical plug-in system, the connector plug can be firmly connected to the charge controller. If necessary, the solar bag can be removed, hung up or placed in the sun. You simply plug the two Anderson mating plugs together and the SunFolder is already connected to the charge controller. It couldn't be faster or more practical!
Self-sufficiency with solar cells from SunPower
The SunFolder solar bags from the WATTSTUNDE® series contain high-quality modules with SunPower solar cells, which deliver the best results and ensure a high energy yield. Solar bags are suitable for all self-sufficient battery applications such as RVs, campers and tents, boats and sailboats, RVs, vans (including off-road vehicles such as the Land Rover Defender) and all off-road vehicles.

frequently asked Questions
Ideally, the LSD batteries have a lifespan of 15-20 years, but as we all know, the Power Stations are consumables, so the lifespan of them depends on the usage habits. However, we can promise that after the specified cycles (full charge and discharge), the devices will have 80% capacity left. The cycle times can support the customer for 5-6 years depending on the power station when used as described in the manual.
First, make sure your power station is connected to the EcoFlow app in internet mode. Second: Go to the Firmware section in the settings of the power station that you want to update. Check for the latest firmware and follow the steps to complete the upgrade.
That depends on the combined voltage and current of the solar panels you choose. It's fine as long as the solar panels use solar connectors and their combined voltage and current is between 10-150 volts and under 15 amps. For example, you can connect up to 3 x 400W solar panels to the Delta Pro (EU). You can find more information on our Energy Blog
When your portable power station is plugged into the wall outlet, all connected electronic devices are powered by the mains and not by the battery. If the power supply from the mains is interrupted, e.g. B. in the event of a power failure, the power plant automatically switches to battery power within 30 ms.
All Power Stations except Delta (EU) are compatible.
The EcoFlow Smart Generator is more intelligent than conventional generators. It works with the EcoFlow app so you can control and monitor it remotely. It features an LCD screen for when you're nearby, and you can even preset an automatic start when your Power Station is depleted to a certain level.
In contrast to other generators, the smart generator charges your power station directly with direct current. This results in approximately 10% higher efficiency, saving you time and money.
The Smart Generator was developed to complement the DELTA Pro or DELTA Max, but also works as a traditional gas generator when you need it on its own.
To bridge longer power outages, you can charge your DELTA Pro or Max with the Smart Generator. In this case, a full tank of fuel adds 5.4kWh to your ecosystem.
Portable solar panels are a highly effective, clean and renewable way to charge a portable power station. The EcoFlow 400W portable solar panels have higher wattage than typical solar panels and are more efficient due to their monocrystalline cells. You can string together up to three 400W portable solar panels and use them with a DELTA Pro Portable Power Station to achieve 1200W of power. In addition, the EcoFlow portable power supplies use an MPPT algorithm to ensure a constant power supply. Unlike static solar panels, portable solar panels can be easily moved and oriented in the sky depending on the position of the sun.
