Calculate your system requirements in 60 seconds with our interactive tool: Average Peak Sun Hours: Typical: 3-4 (cloudy areas), 5-6 (sunny areas). Check your location. The detailed formulas and
Product Features: Standardized structure design, menu-type function configuration, photovoltaic charging module, a parallel off-grid switching module, power frequency transformer, and other components can be
Optimizing the use ofrenewable energy: Maximize the use ofphotovoltaic powerduring the day, whileexcess power is storeofor use at night. Peak shaving & Valleyfilling: Supply power to the loaowhen the power grid
Solar radiation of 1,000 W/m2, module temperature of 25°C and solar spectrum air mass of 1.5 is used to define standard conditions. This is generally referred to as a “full sun” condition.
This off-grid sizing calculator simplifies a complex design process into an understandable workflow. While results provide a strong engineering baseline, always verify with real-world site data, local irradiance tables,
Off-grid energy storage cabinet for solar power generation — PWM inverter technology, quasi-sine wave output, stable power supply.
Using your daily energy usage and Peak Sun Hours, and assuming a system efficiency of 70%, the calculator estimates the Wattage required for your off-grid solar system''s solar array.

Empa Solar Energy Europe is a leading energy storage equipment manufacturer and integrator based in Poland, serving the European market. We specialize in C&I energy storage systems for factories and warehouses, industrial battery storage systems for heavy-duty applications, factory energy storage systems (ESS) to optimize production, commercial battery energy storage systems (BESS) for retail and offices, enterprise storage solutions for corporate campuses, industrial park energy storage for multi-tenant sites, commercial battery storage for peak shaving, industrial battery storage systems for backup power, and remote base station power solutions for telecom towers. Our portfolio also includes lithium-ion batteries, system-level battery management systems (BMS), energy conversion systems (PCS), energy storage battery system cabinets, communication cabinets for telecom and data centres, integrated PV-storage systems, distributed energy resources, deep discharge battery technology, and containerised BESS. As a full-service provider, we also offer modular battery racks, backup emergency power, and zero‑carbon microgrids. Our advanced lithium‑ion and sodium‑ion solutions ensure safety, scalability, and high performance for commercial, industrial, and utility projects across Europe.
Our modular energy storage portfolio ranges from compact lithium-ion batteries to 20ft/40ft mobile containers and outdoor all-in-one storage cabinets with IP54 protection. We are a leading energy storage equipment manufacturer, offering communication cabinets for 5G/telecom, server racks for data centers, and IP54 rated enclosures for harsh environments. Our stackable design allows flexible capacity expansion, while our grid-forming technology ensures stable off‑grid operation. Whether for remote base stations, off‑grid power systems, backup emergency power, integrated PV-storage or large zero‑carbon parks, our products feature advanced thermal management, deep discharge cycling, and compliance with European and international standards. We also provide professional energy storage system installation and after‑sales support across Europe.
