Growatt MIC and MIN inverters: models and specifications

Growatt's MIN range is the brand's core offering for UK home solar: single-phase string inverters sold in three main strands. The TL-X models are straightforward grid-tied inverters with no battery connection. The TL-XA models are AC-coupled inverters. The TL-XH2 models are hybrids: they connect a high-voltage battery, and with a separate back-up box they can keep selected circuits running in a power cut¹.

The headline figures a householder will meet are these: maximum efficiency of 98.2% on the smaller MIN models and 98.4% on the larger ones, an IP65 enclosure rating that permits outdoor installation, a noise level of no more than 35 dB(A) on the MIN 5000, and a 10-year European service warranty stated by the manufacturer across the range⁴. A UK distributor lists the MIN 5000TL-X inverter hardware at £397.94, excluding installation⁶.

The MIC range sits below the MIN as Growatt's small-system option, starting at 750 W, and is covered here alongside the MIN because households comparing quotes often see both⁷.

Overview of the MIN series: TL-X, TL-XA and TL-XH2

Three strands make up the MIN family, and the letters after the hyphen are what distinguish them. The TL-X is the plain grid-tied inverter: the MIN 5000TL-X, for example, is described by Growatt as a high-efficiency on-grid inverter without energy storage support, transformerless in topology, with two independent MPPT trackers⁵. The TL-XA strand, covering 2500 to 5000 W, is listed as an AC-coupled inverter and works with the Growatt Monitoring Platform¹. Above 6 kW, the MIN 7000-10000TL-X/X2 carries the same residential PV inverter classification at higher outputs².

The TL-XH2 strand is the battery-ready one. Growatt classifies the MIN 2500-6000TL-XH2 as a Battery Ready Inverter, and describes the wider TL-XH/XH2 series as the most popular single-phase Growatt hybrids for homes: compact, quiet, ready for a high-voltage battery and an emergency power supply³. Growatt's own residential case studies show the TL-X in service, including an Argentine installation powered by the MIN 5000TL-X⁴.

For a household trying to place the MIN among inverter types generally, the TL-X is a string inverter and the TL-XH2 is a hybrid inverter; the wider context is in solar inverters.

Choosing between MIC and MIN for your property

The MIC range is Growatt's answer to very small systems. The MIC 750-3300TL-X/X2(Pro) is classified as a residential PV inverter, and a UK distributor notes that the Growatt range starts with a 750 W inverter, described as perfect for three-panel systems, and includes twin-tracker inverters through the range⁷. A MIC is therefore the candidate where only a handful of panels are going in, or where a roof allows only a small array.

The MIN is the mainstream choice for a full roof. Sizing guidance from the industry puts a 3000 W to 5000 W inverter as the sweet spot for a typical home backup-capable system, which lands squarely in MIN territory¹⁰. For orientation, microinverters from other makers are positioned at new-build houses where a simple solar system is required, which is the same small-system ground the MIC covers¹¹.

The practical dividing line is array size. A three-panel system is MIC scale; a 10 to 14 panel roof, the common UK installation, needs a MIN in the 3.6 to 6 kW class. Households weighing the two approaches side by side can read microinverters vs string inverters, and the sizing question in full is covered at what size solar system a home needs.

The XH2 hybrids: 2.5 to 6 kW, battery-ready with backup

The MIN 2500-6000TL-XH2 range runs from 2.5 to 6 kW and is built around one idea: the inverter is installed first, the battery comes when the household wants it. Growatt states that the high-voltage battery can be added at any later point without replacing the inverter, and that the battery interface makes the system easily extendable into storage in the future without extra device or retrofit cost³. That is the whole point of buying an XH2 rather than a plain TL-X.

The battery side is specified precisely. The MIN 2500-XH2 and MIN 4600-XH2 are hybrid inverters working with high-voltage batteries, and Growatt lists the ARK 2.5H-A2 (HV) and APX 5.0P-B1 (HV) as the compatible models⁸. The wider range is listed as working with the ARK XH battery, and an ARK battery set for XH is stated as compatible with Growatt MIN-XH and MID-XH hybrid inverters³. On the charging side, the MIN 5000TL-XH offers 5 kW full-power battery charge⁴.

Backup power is not inside the inverter box. It is provided by the SYN 50-XH-10 back-up box, which Growatt states keeps selected circuits supplied when the grid fails; the box is matched to the XH-series hybrid inverters rather than being universal⁸. The MIN 6000-XH2 tops the range at 6 kW rated AC power with two independent MPPT trackers¹⁵.

What this means in practice: a household can install an array with a MIN 4600-XH2, run it grid-tied for a year, then add an ARK battery and the SYN box without touching the inverter. The path is set out in more depth at adding battery storage to solar.

Technical data: efficiency, voltages and currents

The electrical figures are close across the range, with the efficiency figure varying by power rating. The MIN 5000TL-X is listed at a maximum efficiency of 98.2% for the 2.5, 3 and 3.6 kW variants and 98.4% for the 4.2 to 6 kW variants; the XH2 hybrids are listed at 98.2 to 98.4%⁵. Start-up voltage is 100 V on both the TL-X and the XH2 models, meaning the inverter begins producing from first light rather than waiting for full sun⁵.

The 13.5 A per-MPPT input current on the TL-X matters when pairing with modern high-current panels: it sets how many panels can sit on each string. How these figures fit the wider picture of reading a datasheet is covered at solar panel specifications.

Physical build: enclosure, cooling and weight

The build is consistent across the range. The MIN 5000TL-X and the XH2 hybrids carry an IP65 ingress protection rating, which Growatt states allows indoor and outdoor installation; a UK distributor makes the same point about the Growatt range generally⁵. IP65 means dust-tight and protected against water jets, so an outside wall is within rating, though a sheltered position remains the sensible choice for any electronics.

Cooling on the XH2 hybrids is by natural convection, with no fan⁸. That is reflected in the noise figure: the MIN 5000TL-X is listed at no more than 35 dB(A), which is quieter than a typical refrigerator and low enough for a utility room or hallway cupboard⁵.

One figure is genuinely unclear. Growatt's own pages list the weight of the MIN 5000, the MIN 2500-XH2 and the MIN 4600-XH2 at 10.8 kg in some places and 13.20 kg in others; the two figures differ and neither is corrected⁵. Either way it is a one-person lift onto a bracket, but not a one-hand job.

Tracking output via ShinePhone and ShineServer

Monitoring runs through two linked products: the ShinePhone app, described by Growatt as a system monitoring app for users with simple WiFi configuration, and the ShineServer portal¹⁶. The MIN models are listed with ShinePhone / ShineServer monitoring over WiFi⁵. Where a system needs a connection added, the Shine WiLAN-X2 is designed to work with Growatt inverters and energy storage systems that support that monitoring, and lets a household monitor production, consumption and battery state remotely in the app and the portal¹⁷.

What the app shows depends on what is connected. On a battery system, the ShinePhone app and the ShineServer portal show the state of charge, the charge and discharge power and the operating history, monitored through the connected inverter¹³. The SYN 50-XH-10 back-up box, once connected, becomes part of a system monitored in the same app and portal¹⁴.

The dependence to note: remote monitoring needs home broadband, a WiFi link to the inverter and Growatt's platform. The inverter itself does not stop working without them; only the visibility does. The general picture of watching a system's output is at monitoring a solar PV system.

Guarantee: 10 years of cover across Europe

Growatt states a 10-year European service warranty across the MIN range, per the manufacturer's terms. The figure appears identically for the MIN 5000TL-X, the MIN 2500-XH2, the MIN 4600-XH2 and the MIN 6000-XH2⁵. The batteries carry the same term: an ARK battery set for XH is covered by a European service warranty of 10 years, per the manufacturer's terms¹³.

Two things are worth holding in mind. First, this is a manufacturer's warranty stated on the maker's own product pages, not an independent guarantee scheme, and it is described as a European service warranty, so its administration runs through Growatt's European operation rather than a UK body. Second, the warranty covers the hardware; the small print of what counts as a defect sits with the manufacturer's terms, which a buyer receives with the product.

Ten years is in line with the better end of the string inverter market, where lifespans and warranties are discussed at solar inverters. A comparison against a close rival brand is at Growatt vs Solis.

Price and where to buy in the UK

There is no installed price for a Growatt MIN system: quotes come from installers after a survey. The hardware figures that exist are distributor listings. A UK distributor lists the MIN 5000TL-X inverter at £397.94⁶. Smaller MIN models appear at lower figures that differ between listings: the MIN 3000TL-X appears at £316.01 in one listing and £379.21 in another, and the MIN 2500TL-X at £358.14 and £298.45, so any single number should be read as indicative rather than fixed⁶. The VAT position is not stated in these listings, and they cover the inverter alone, not fitting, scaffolding or certification.

Availability is straightforward: Growatt states the MIN 5000 and the MIN 2500-XH2 are available at Growatt.tech, its European distributor channel, and UK solar distributors stock the range⁸. The wider cost picture for a complete system, panels and installation included, is at how much solar panels cost, and the payback side at solar panel savings and payback.

How the MIN supports a home's self sufficiency

A plain TL-X model is honest about its limits: it is an on-grid, grid-tied inverter without energy storage support, so the household generates while the sun shines, self-consumes what it can and exports the rest, but when the grid fails the system stops⁵. The inverter also depends on the grid connection itself, since connection follows the G98 and G99 process set out at connecting solar to the grid.

The XH2 hybrids change that picture in two steps. The battery step, an ARK or APX high-voltage unit added at any point without replacing the inverter, shifts consumption from daylight hours to evening, cutting bought electricity⁸. The backup step, the SYN 50-XH-10 back-up box, keeps selected circuits supplied when the grid fails, which is the difference between a power cut meaning candles and a power cut meaning the fridge and the router still run⁸. What solar can and cannot do in an outage generally is covered at do solar panels work in a power cut.

The dependencies that remain are real and worth naming. The inverter is grid-tied hardware from a single manufacturer, monitored through that manufacturer's app and platform over the household's own broadband, with a warranty administered by the maker's European service operation⁵. The battery must be a Growatt high-voltage model matched to the inverter⁸. None of that is unusual for the market, but a household aiming at energy independence should see it plainly: the MIN range reduces dependence on a supplier's daytime electricity, and the XH2 with its back-up box extends that to outage cover, while the equipment, the monitoring and the warranty each remain tied to one company. The wider frame for that trade-off is at solar panels and household energy independence, and the starting point for the whole subject is the solar PV guide.
