Jaka pojemność magazynu energii jest optymalna? Jak obliczyć kWh i nie przepłacić!

Welcome to the ZeptoBox channel! In today's episode, Waldemar Wawer answers one of the most frequently asked questions: what energy storage capacity should you choose? The costs of an energy storage facility are directly linked to its optimal capacity, so it all depends! You'll learn how to approach costs sensibly and avoid overinvesting. In this episode, you'll learn: Why optimal storage capacity isn't the same as a common-sense approach to costs. What data (electricity bills, hourly consumption) is needed for optimal storage selection? What is the "three-day rule" for selecting energy storage capacity? What is NetMetering and how does it compare to storage? What is the difference between storage capacity (kWh) and storage power (kW) and why you need to be careful! About the optimal operating range of LiFePO4 storage facilities (20%-80% of nominal capacity). Why high capacity and low charging power (kW) can be a problem. How much electricity do inverters (e.g., Deye vs. Anenji) consume for their own needs and how does this affect the storage system?
