Contact & Help Center
High-performance battery storage systems and wind turbines at your fingertips. Do you have questions about our products or need a consultation on a technical solution? Feel free to contact me directly—you are always speaking with the person who designs and builds the systems.
Why Work with Me?
- Personal Approach & Guarantee: I am not an anonymous wholesale company. Everything I design and assemble passes through my hands, and I stand behind it with my own name.
- Flexibility & Nationwide Delivery Across the Czech Republic: Because I frequently travel across the country for installations, I can efficiently combine deliveries and setups—transport can often work out very favorably through the combination of multiple clients at once.
- Personal Pickup & Testing: I am based in Jilemnice, Czech Republic, where you can personally inspect, test, and have everything demonstrated in detail upon prior arrangement.
- Hands-on Experience: I pride myself on deep industry knowledge—from energy accumulation to efficient recycling and secondary raw materials. I know what technologies need to run without interruptions.

🟢 Frequently Asked Questions (FAQ & Advisory)
Cheap equipment looks tempting at first glance, but a battery storage system must safely serve for 15+ years. Real quality relies on cell grade, reliable monitoring, warranty support, spare parts availability, and easy serviceability. With us, you know exactly what you are buying—built on verified components with full support.
### When is a Deye or Victron system the optimal choice?These brands represent the absolute pinnacle for residential hybrid installations and demanding off-grid systems. They offer maximum flexibility, great compatibility with low-voltage 48V setups, and seamless integration of home backup during grid failures.
### Can I add a battery to my existing solar system?Yes, adding a battery to an already running photovoltaic system is very often possible and represents a highly efficient step to increase self-sufficiency and store previous surplus energy.
### Will the solar power plant work during a grid blackout?Standard on-grid PV systems disconnect during a power outage for safety reasons. For your home to keep running, you need a properly designed hybrid system with backup power (EPS) functionality or a fully off-grid setup with battery storage.
### Can I monitor the entire system on my mobile phone?Yes, all recommended inverters and BMS units allow you to conveniently track energy flows, battery state of charge (SoC), and daily statistics in real-time directly via a mobile app from anywhere in the world.
### How do delivery, installation, and system handovers work?Because I travel extensively across the country, installations and deliveries are arranged individually. We frequently combine multiple jobs within the same region, significantly lowering transport costs. The process always includes personal activation, configuration, and a live demonstration at your location.
### Is it possible to inspect the equipment personally before purchase?Yes! I am based in Jilemnice (Liberec Region). Upon prior phone agreement, you are warmly welcome—I will gladly show you everything, explain the details, and demonstrate it in operation.
🟢 Section 1: Safety & Battery Myths
Expert Answer: No. LiFePO4 (Lithium Iron Phosphate) has exceptional thermal and chemical stability and is non-explosive. It uses a completely different chemistry than consumer electronics like phones or laptops (Lithium Cobalt Oxide), which are prone to overheating and ignition.
### Can I discharge a LiFePO4 battery to 100% capacity without damaging it?Expert Answer: Yes. Unlike lead-acid batteries where depth of discharge past 50% drastically cuts lifespan, LiFePO4 handles deep cycles without damage. A 100Ah LiFePO4 battery delivers comparable usable energy to a 200Ah lead-acid battery.
### Does it make sense to wait for "miraculous new technologies" in batteries?Expert Answer: Waiting for breakthrough technologies (like solid-state cells) could take another 10 years, during which you would waste a fortune on grid electricity. Today's LiFePO4 systems are mature, extremely safe, and proven technology with a lifespan exceeding 8,000 cycles. Investment payback starts right now.
### What is the realistic lifespan and degradation of LiFePO4 cells over time?Expert Answer: Premium Grade A cells (such as EVE) typically retain 80% of their original capacity after 8,000 cycles. In real home use, this translates to 15 to 20 years of reliable service, and the batteries continue to function past this threshold with only a gradually declining capacity.
🟢 Section 2: Assembly & Battery Care (Technical Background)
Expert Answer: From the perspective of maximum capacity and precision, yes. It is the process of equalizing the voltage of all cells to 100% capacity prior to series connection (16S) so that the pack harmonizes perfectly and the BMS has accurate telemetry.
### How does communication between the BMS and the inverter work (CAN/RS485)?Expert Answer: It ensures a direct data link—the inverter precisely knows cell temperatures, state of charge (SoC), and permitted current limits. This eliminates configuration risks and maximizes overall system longevity.
### What is the ideal operating temperature for a battery storage installation?Expert Answer: The ideal range is 15 °C to 25 °C. Beware of freezing temperatures—charging LiFePO4 cells below 0 °C without active heating permanently damages them. Similarly, long-term heat exposure above 35 °C unnecessarily shortens their lifespan.
