What PowerFlow Energy does
PowerFlow Energy Ltd is a privately held UK manufacturer founded in 2014 and based in Hereford, specializing in solar power diverters that redirect surplus solar PV generation to resistive heating loads (typically immersion heaters) instead of exporting to the grid. Its product portfolio centers on three single- and three-phase diverters — FAZE ECO (3kW), E.R.S PRO (6kW), and FAZE THREE (12kW) — priced from £249.95 to £1,199.90 and supported by a catalog of accessories including current clamps, extension kits, and replacement parts. The company's proprietary F-POINT Technology® enables export measurement at <200ms intervals and supports a battery compatibility mode for prioritizing third-party storage systems, giving the hardware differentiated integration capabilities relative to standard diverters.
The business operates a direct-to-consumer e-commerce model through powerflowenergy.com with a parallel trade account program for UK installers and electricians; products are designed and manufactured in the UK and carry CE, RoHS, and BS EN 61000 compliance certifications, along with the Made in Britain mark. Revenue is generated entirely through one-time hardware sales with no subscription or recurring component, and warranty extensions are free upon registration. Primary customers are residential solar PV owners seeking to maximize self-consumption and reduce energy bills, with an emerging secondary segment in larger domestic and small commercial three-phase applications via the FAZE THREE line. The company previously attempted battery storage with a GEN 1 product line launched in 2016 and discontinued in 2017, refocusing engineering on power diversion, and has remained founder-operated without disclosed external institutional investment.

PowerFlow Energy product offering
Product offeringCore offering
PowerFlow Energy designs, develops, and manufactures solar power diverter hardware (FAZE ECO 3kW, E.R.S PRO 6kW, FAZE THREE 12kW three-phase) that automatically redirects excess solar electricity from grid export to resistive heating loads such as immersion heaters and home heating systems. The company sells direct-to-consumer through its own e-commerce website, with a trade account program for installers and electricians, and also offers compatible accessories and replacement parts. All products are made in the UK and use the company's patented F-POINT Technology® for export measurement and control.
Product overview
PowerFlow Energy is a UK-based manufacturer of premium solar energy storage and power diversion products. Their core product portfolio consists of three main power diverter lines: FAZE ECO (3kW single-phase, entry-level), E.R.S PRO (6kW flagship single-phase with advanced features), and FAZE THREE (12kW three-phase for commercial/domestic use). These devices divert excess solar energy to heating loads like hot water cylinders instead of exporting to the grid, maximizing self-consumption and savings. The products utilize proprietary F-POINT technology with 98% efficiency and <200ms reaction time. PowerFlow also offers a range of accessories including current clamps, extension cables, AUX connectors, and replacement parts. The company maintains support for archived products including earlier E.R.S generations and Sundial battery storage systems.

PowerFlow Energy competitors and assessment
Company assessmentBroad incumbents
- Enphase Energy: Enphase's IQ8 microinverters and IQ Battery products come with export-limiting and load-management features built into the inverter firmware, offering an integrated alternative to a standalone power diverter. Enphase is a broad incumbent in residential solar electronics targeting similar installer channels and the same self-consumption outcome as PowerFlow's products.
- Tesla (Powerwall): Tesla's Powerwall battery system pairs with solar PV to maximize self-consumption, effectively substituting the battery-based alternative to PowerFlow's diverter-based self-consumption approach. While PowerFlow positions hot-water diversion as a lower-cost alternative, Tesla remains the category-defining benchmark for residential energy storage and shapes consumer expectations in the UK market.
- Fronius: Fronius manufactures residential and commercial inverters with built-in export limitation and dynamic load management features, which substitute for a discrete power diverter in new PV installations. As an established European inverter brand, Fronius competes indirectly with PowerFlow by absorbing the diverter function into its inverter platform for installers specifying premium systems.
- SolarEdge: SolarEdge is a leading inverter and power optimizer manufacturer whose optimizer-level visibility of PV output enables built-in export control and load diversion, making its systems a substitute for a discrete power diverter. While PowerFlow's hardware sits downstream of the inverter, SolarEdge's integrated approach competes for the same self-consumption value proposition, especially in new-build PV installations.
Emerging players
- Immersa (renovagen / solar controller makers): Various smaller UK and EU manufacturers produce immersion and load-diverting controllers that compete at the entry-level price point where PowerFlow's FAZE ECO sits. These products share the same installer channel and price band and represent an emerging tier of low-cost alternatives in the domestic solar retrofit market.
- Sunsynk: Sunsynk produces hybrid inverters and batteries with built-in energy management and load control features, positioning its products as a one-stop alternative to a separate power diverter in residential and light-commercial solar systems. It competes with PowerFlow for the same installer-driven UK retrofit solar market and overlaps significantly on the energy-management software layer.
- Open Energy Monitor: Open Energy Monitor produces open-source energy monitoring hardware that competes with PowerFlow's Sundial Energy Gateway for visibility into solar export and household consumption. While not a direct diverter, it overlaps on the energy-management and monitoring layer that PowerFlow has integrated into its diverter products, appealing to technically inclined installer and DIY customers.
Direct peers
- Marlec (iBoost+): Marlec's iBoost+ is a UK-designed solar energy diverter that redirects surplus PV to hot water cylinders, directly overlapping PowerFlow's FAZE ECO and E.R.S PRO use case. Both products compete for the same residential solar installer channel in the UK and target the same pain points (grid export, hot-water energy costs).
- MyGridGB (Eddi / myenergi): myenergi's Eddi is a direct competitor to PowerFlow's diverter lineup, offering a micro-generated-energy diverter that redirects surplus solar to immersion heaters with similar features (variable rate, boost functions, battery compatibility in newer models). Both target UK residential PV owners via installer trade and D2C channels with comparable price points and product positioning.
- GivEnergy: GivEnergy is a UK-headquartered manufacturer of hybrid inverters, batteries, and energy management systems serving the same residential solar installer base. While its core focus is battery storage rather than pure diversion, its hybrid inverters incorporate load management and export control that compete with PowerFlow's diverter logic, and its UK manufacturing roots and trade channel compete for similar customers.
