## About
PowerGO designs, installs and services PV systems, energy storage and reactive-power compensation for homes, businesses, farms and developers. Based in Kliny near Poznań. All prices and figures on the site come from a single internal source of truth.

## Reactive power & power quality
- [Reactive power compensation — how it works](https://www.powergo.pl/kompensacja-mocy-biernej): why operators charge for reactive energy (tg φ) and how compensation removes it.
- [SVG — active reactive-power compensator (ASVG)](https://www.powergo.pl/kompensator-svg): dynamic, bidirectional compensation for industry and PV; SVG vs capacitor banks.
- [Reactive-power measurement](https://www.powergo.pl/pomiary-i-analiza-energii): measuring reactive power and power factor with an audit-class analyzer.
- [Energy-consumption analysis](https://www.powergo.pl/analiza-zuzycia-energii): load-profile analysis — active/reactive power, tg φ, harmonics, savings.

## Photovoltaics
- [Photovoltaics — hub](https://www.powergo.pl/fotowoltaika): PV for home, business, farm and developers.
- [PV for business](https://www.powergo.pl/fotowoltaika-dla-firm): autoconsumption, reactive-power savings, financing.
- [PV for farms](https://www.powergo.pl/fotowoltaika-dla-rolnika): sizing for seasonal farm loads and support programs.
- [PV for developers](https://www.powergo.pl/fotowoltaika-dla-deweloperow): PV in new buildings, common areas, tenant prosumer.
- [Ballast mounting for flat roofs](https://www.powergo.pl/konstrukcja-balastowa-fotowoltaika): PV mounting without roof penetration; south vs east-west layout.
- [Grid overvoltage 253 V (inverter shutdown)](https://www.powergo.pl/za-wysokie-napiecie-fotowoltaika): why inverters shut off at 253 V and how to fix it.
- [Inverter configuration and service](https://www.powergo.pl/konfiguracja-falownika): mounting, grid settings P(U)/Q(U), monitoring, backup.

## Energy storage
- [Energy storage — guide](https://www.powergo.pl/magazyn-energii): how storage works, sizing, payback, brands.
- [SolarEdge energy storage](https://www.powergo.pl/magazyny-energii-solaredge): SolarEdge Home 48V, Energy Bank; why SolarEdge (MLPE, mySolarEdge AI).
- [SolarEdge Nexis — next-gen inverter + storage](https://www.powergo.pl/solaredge-nexis): hybrid inverter 8–20 kW (SiC), modular HV battery up to 78.4 kWh, whole-home backup; Nexis vs Home Hub.

## Electromobility (EV charging)
- [EV chargers and wallboxes with installation](https://www.powergo.pl/elektromobilnosc): wallbox for home and charging stations for business, charging from PV and storage, dynamic load management (DLM) to protect the grid connection, subsidies.

## Energy communities for developers (Osiedle Energetyczne)
- [Osiedle Energetyczne — energy communities for new estates](https://www.powergo.pl/osiedle-energetyczne): PV, battery storage (BESS) and a legal/settlement model — energy cooperative (rural and urban-rural municipalities) or collective/tenant prosumer (urban buildings) — so a whole estate produces, stores and settles its own renewable energy; PowerGO's answer to EPBD compliance (solar on all new residential buildings from 31 Dec 2029, zero-emission building standard from 1 Jan 2030).
- [EPBD status tracker](https://www.powergo.pl/osiedle-energetyczne/epbd-status): live tracker of EPBD transposition status in Poland — canonical source for regulation status.
- [Financing for estate energy systems](https://www.powergo.pl/osiedle-energetyczne/finansowanie): support programs with current dates and statuses.
- [FAQ — Osiedle Energetyczne](https://www.powergo.pl/osiedle-energetyczne/faq)

## Audits
- [Energy and PV audit — Poznań and Wielkopolska](https://www.powergo.pl/audyt-energetyczny): PV and building audits, measurements, report with prioritized recommendations.

## Tools (calculators)
- [AC cable and protection calculator](https://www.powergo.pl/poradniki/dobor-kabli-i-zabezpieczen): rated current, protection, cable cross-section for inverters and SVG.
- [AC voltage-rise calculator (253 V)](https://www.powergo.pl/kalkulatory/wzrost-napiecia-ac): voltage rise on the AC run; is the cable or the grid to blame.
