FREQUENTLY ASKED QUESTIONS
Everything you need to know about off-grid PV solutions
A stand-alone PV system is an off-grid photovoltaic system that generates electricity and stores it in batteries. This type of solar system, as an off-grid solution, provides energy to properties without a mains connection – ideal for garden sheds, holiday homes, mountain cabins, or mobile applications such as motorhomes and boats.
The storage capacity should be at least 1,2 times your daily electricity consumption. For a consumption of 8 kWh per day, we recommend approximately 10 kWh of usable storage capacity to bridge periods of bad weather. Our hybrid solar systems offer storage capacities from 5,12 kWh to 20,48 kWh.
No, a true off-grid photovoltaic system does not need to be registered with the grid operator. The system operates completely autonomously as an off-grid system and does not feed any electricity into the public grid.
A stand-alone PV system with grid switching combines self-sufficient off-grid operation with a grid connection as a backup. Under normal operating conditions, the system is self-sufficient; when the battery is depleted, it automatically switches to grid power. This ensures maximum security of supply without compromising self-sufficiency.
Yes, our hybrid systems are modular. You can add additional solar panels or storage modules at any time. The hybrid inverters from Sofar and Solis support flexible expansions up to the maximum system capacity.
Our three-phase hybrid inverters generate a pure sine wave, just like a standard wall outlet. This allows you to power all common household appliances: lighting, refrigerators, washing machines, pumps, power tools, and sensitive electronics. The system should be appropriately sized.
A wide selection of off-grid PV systems for self-sufficient power supply
A stand-alone photovoltaic (PV) system enables off-grid power generation in locations without a connection to the public grid. At PVundSO, you'll find off-grid photovoltaic solutions for various power classes from 6 kW to 20 kW. Whether for a garden shed, mountain cabin, or camper van, a stand-alone solar system reliably produces electricity for your own use. All systems operate as closed off-grid systems and do not require registration with the grid operator.
Our product range includes perfectly matched complete sets with solar panels, hybrid inverters, and storage batteries. We carry off-grid solar solutions from brand-name manufacturers such as JA Solar, Sofar, and Hoymiles, guaranteeing long-lasting quality. An integrated charge controller protects the batteries from overcharging and deep discharging. Our experienced electrical engineers have tested all systems for optimal suitability in real-world applications.
From complete sets to individual components, all variants are available.
We offer off-grid solar systems as ready-to-use packages or as individual components for customized projects. Our hybrid solar systems with storage capacities from 5,12 kWh to 20,48 kWh cover a variety of consumption profiles. For those looking to expand their off-grid PV system, we offer additional battery modules and compatible solar panels.
When selecting an off-grid PV system, daily electricity demand and the desired autonomy time play crucial roles. The following overview shows typical configurations for various applications.
| Plant performance | Storage capacity | Recommended application |
|---|---|---|
| 6 kW | 5,12 kWh | Garden shed, weekend house |
| 8,5 kW | 10,24 kWh | Holiday home, small commercial properties |
| 10 kW | 10,24 kWh | Permanently inhabited properties |
| 15 kW | 15,36 kWh | Larger households, agriculture |
| 20 kW | 20,48 kWh | Commercial use, self-sufficient residential projects |
Our three-phase hybrid inverters enable even load distribution and are also suitable for demanding consumers such as pumps or power tools.
Solar off-grid system for garden, holiday home and motorhome
An off-grid solar system is suitable wherever there is no electricity connection or where grid connection would be prohibitively expensive. Garden sheds benefit from small off-grid solar systems that power lighting, lawnmowers, and pond pumps. For vacation homes, we recommend larger off-grid photovoltaic solutions with sufficient storage capacity to cover extended periods of bad weather.
Mobile applications such as motorhomes, boats, and campervans rely on flexible solar panels and compact storage solutions. An off-grid solar system with a 12V or 24V system voltage charges the onboard battery and simultaneously powers 230V devices via an off-grid inverter. In our shop, we carry the Jackery HomePower series with portable storage/inverter combinations and expandable battery capacity for mobile use.
Combine your off-grid solar system with a suitable storage solution directly.
The energy storage system is the heart of every off-grid solar power system. Without a battery, only 20 to 30% of the generated energy can be used, as solar irradiance and energy consumption rarely coincide. We offer Pylontech Force H3 high-voltage batteries with capacities from 10,24 kWh to 15,36 kWh in a compact design.
When sizing a stand-alone PV system, a rule of thumb is that the storage capacity should be at least 1,2 times the daily electricity demand. An average daily consumption of 8 kWh therefore requires approximately 10 kWh of usable battery capacity. Our three-phase Solis S6 hybrid inverters with 8 kW to 15 kW output intelligently control charging and discharging, ensuring a pure sine wave, just like a standard wall outlet.
Secure attractive offers for off-grid systems with grid switching now
A stand-alone PV system with grid switching combines the advantages of self-sufficient systems with the security of the public grid. These hybrid systems operate completely independently of the grid under normal conditions, but automatically switch to grid power when the battery is depleted. This ensures maximum security of supply without compromising energy independence.
We offer off-grid PV systems with attractive price advantages and free shipping on orders over €100. All inverters have the necessary certifications for the German market. Our telephone support is available to assist you with any technical questions regarding the design of your off-grid PV system. Order your off-grid system online at a great price and benefit from short delivery times directly from our warehouse.
