A setting in the menu is not distribution network operator consent." } }, { "@type": "Question", "name": "Does selecting Rule 5 replace a G99 application?", "acceptedAnswer": { "@type": "Answer", "text": "No. Selecting Rule 5 applies a grid code inside the inverter. It does not submit an application, set an export limit, or prove that the firmware on the wall matches a type-test entry. The distribution network operator still has to see the capacity, the phase arrangement and any export constraint for that site. A later change of grid code can leave the tested protection settings different from the settings in use." } }, { "@type": "Question", "name": "Can this 12 kW hybrid be connected under G98?", "acceptedAnswer": { "@type": "Answer", "text": "Nothing in the material used here establishes that this inverter can be connected on the G98 route. G98 is generally used for fully type-tested microgeneration up to 16 A per phase, and a 12 kW hybrid should not be assumed to be a G98 device. G99, as discussed here, is a Great Britain recommendation and should not be treated as the connection rule for Northern Ireland. MCS certification and any export-tariff eligibility are separate questions, and neither follows from a selectable grid code." } }, { "@type": "Question", "name": "Is an external Loss of Mains relay required?", "acceptedAnswer": { "@type": "Answer", "text": "No additional external Loss of Mains relay is specified for the standard G99 configuration. The inverter is described as having integrated anti-islanding and grid monitoring when operating under Rule 5. That is not a promise that every network operator, every multi-inverter site, or every altered-settings case will accept the inverter alone. If the manufacturer's instructions for the installed firmware, or the connection offer for that site, ask for an external relay, the relay is part of the job." } }, { "@type": "Question", "name": "Why does whole-house EPS still need an external automatic transfer switch?", "acceptedAnswer": { "@type": "Answer", "text": "In off-grid mode the GRID port will not provide output, while the EPS/LOAD port provides the backup supply. An external automatic transfer switch moves the house load from the grid supply to that EPS supply, and back again when the grid returns. The two ports must not be tied together or treated as sources to parallel. Backup also needs a battery or other source the inverter can use, and the circuits that transfer have to stay within the stated UPS output." } }, { "@type": "Question", "name": "Is the 100 A passthrough the same as backup power?", "acceptedAnswer": { "@type": "Answer", "text": "No. The stated 100 A continuous AC passthrough is the grid-side current the inverter is said to carry while the grid is present. It is not 100 A of battery or solar backup, and a passthrough claim does not raise the incoming cut-out fuse. The stated backup limit is the 12 kW UPS output, which is not permission to run every circuit at once. Phase count is not established here, so that kilowatt figure should not be converted into an assumed backup current. Confirm both figures on the datasheet and nameplate for the exact variant." } }, { "@type": "Question", "name": "What happens to live, neutral and earth when the inverter transfers to EPS?", "acceptedAnswer": { "@type": "Answer", "text": "Both live and neutral are stated to open on transfer to off-grid EPS, and an internal neutral-earth bond is stated to be applied so the islanded supply has a local earth reference. On a PME supply, also called TN-C-S, island-mode earthing has to be designed around that bond and that disconnection. The bond is not, by itself, a complete PME backup design, and whether a separate earth electrode is required is not established here. If the transfer switch also switches neutral or closes an earth link, the two devices must be specified as one system so the island has one neutral-earth bond, not two or none. Residual-current devices that were correct on the grid may also need another look on the backed-up side." } }, { "@type": "Question", "name": "What should be agreed before the equipment is ordered?", "acceptedAnswer": { "@type": "Answer", "text": "Agree the transfer switch before it is ordered, including its poles, whether it switches neutral, and whether it closes an earth link of its own. Agree the backed-up circuit list at the same time, because a whole-house label is not the same as a load that can stay within the stated 12 kW UPS output. The installer should confirm that Rule 5 is still the G99 selection on the installed firmware, select it before protection tests, and record the setting used. Before the ENA device record for code LUXPO/19557/V1/A2 is cited, the manufacturer, model, firmware and phase arrangement need to match the nameplate." } } ], "about": { "@id": "https://kilowatts.uk/resources/does-the-gen-pro-lb-eu-12k-support/#content" } }, { "@type": "WebPage", "@id": "https://kilowatts.uk/resources/does-the-gen-pro-lb-eu-12k-support/#webpage", "url": "https://kilowatts.uk/resources/does-the-gen-pro-lb-eu-12k-support/", "encoding": [ { "@type": "MediaObject", "encodingFormat": "text/markdown", "contentUrl": "https://kilowatts.uk/resources/does-the-gen-pro-lb-eu-12k-support.md" }, { "@type": "MediaObject", "encodingFormat": "application/ld+json", "contentUrl": "https://kilowatts.uk/resources/does-the-gen-pro-lb-eu-12k-support.schema" } ], "name": "GEN PRO-LB-EU 12K – UK whole-house EPS", "headline": "GEN PRO-LB-EU 12K – UK whole-house EPS", "description": "The GEN PRO-LB-EU 12K supports G99 with Rule 5, integrated anti-islanding and an internal N-PE bond.
