Mirafit - First Time Home Gym

Mirafit - First Time Home Gym

Looking for some advice/sanity check from anyone who has gone down a similar route or owns this kit.

I’ve currently got a heavily cardio-biased setup in my garage, a road bike on a turbo trainer for Zwift and a rowing machine. It’s been great for endurance, but I need to address the glaring strength imbalance and actually get back to heavy compound movements (squatting, bench pressing, overhead work, etc.).

I’m currently eyeing up a basket on Mirafit totaling around £2,100:

- 18 x Sets of Mirafit 20mm Rubber Gym Floor Mats (£34.95 / set of 2), planning to floor out the garage space properly.

- 1 x Mirafit Home Gym Rack Package (Orange) (£1,099.95), includes the power rack, adjustable bench, barbell, bumper plates, and integrated cable pulley setup.

- 1 x Mirafit 6 Pair Hex Dumbbells + Storage Tree Kit (£299.95), for accessories, isolation work, and quick workouts.

Questions

Is buying a pre-bundled package like this a "cheap shortcut"? Or is it actually a solid, sensible way to get everything sorted in one shipment without spending weeks hunting down individual parts?

Floor Mats Check: 20mm rubber mats, are these thick enough for dropping deadlifts on standard garage concrete, or should I be pairing them with horse stall mats/a plywood platform?

Mirafit Rack & Cable Setup: For those who have this specific rack package, how’s the pulley system and bench held up over time? Any regrets or things you wish you’d upgraded out of the gate?

Endorsements/Alternatives: If you started with a similar setup to complement a cardio-heavy background, would you endorse this exact kit, or suggest swapping out specific pieces?

Appreciate any thoughts, feedback, or harsh truths before I hit the checkout button! Cheers!

Quote Check: 17.64kWp Aiko + 18kWh Sigenergy, £18.6k

Area: Fife, Scotland

Panels: 36 x Aiko Neostar 3S+ 490W monocrystalline (17.64kWp), 18 per roof face

Optimisers: 10 x Tigo TS4-A-O due to early morning shading on one side; full sun by around midday

Battery: 2 x Sigenergy SigenStor BAT 10.0 (18.08kWh total)

Inverter: Sigenergy SigenStor 10kW single phase hybrid

Usage: 4,863kWh/year currently; ~6,800kWh including EV

Export limit: G99 application for 10kW being submitted; DNO limit TBC

Supply: Single phase

Expected generation: ~12,500kWh/year; final shading-adjusted MCS report to follow

Tariff: Currently Utility Warehouse; planning to move to an appropriate smart solar/EV tariff, likely Octopus or similar, using cheap overnight electricity for EV charging/battery arbitrage

Price: £18,591.56 total

Includes: Panels, inverter, batteries, optimisers, mounting, new 50m 16mm² SWA between garage/house, excavation/ducting/backfill/reinstatement, consumer unit/protection, MCS design/certification and G99/DNO application

Excluded: DNO connection charge if applicable; backup power

Warranty: 6-year insurance-backed workmanship; 30-year Aiko product/performance warranty

Payback: ~7.5 years in OpenSolar, although this doesn't fully capture battery tariff arbitrage and final shading-adjusted modelling is still to come

Future plans: EV and potentially ASHP

We've compared several installers/specifications and are pretty much settled on this subject to an acceptable DNO response.

Any crazy flags? It's a bigger setup, to me anyway, so struggled to gauge if the price scaled efficiently or proportionally.

Quote Check – Fife, Scotland

What do you think about the below? I'd note that I feel like I sound like I know what I'm talking about, though honestly topping out in terms of my understanding so looking for perspective and/or validation. Thanks!

Location: Fife, Scotland
Panels: 18 × LONGi all-black 480W panels, exact model to be confirmed
Array size: 8.64 kWp
Roof layout: 9 south-east-facing + 9 north-west-facing on a detached garage
Battery: 4 × EcoFlow 5 kWh batteries – 20 kWh total capacity
Inverter: EcoFlow 3.68 kW hybrid inverter, assume Power Ocean (tbc)
Supply: Single-phase
Annual electricity usage: est. 6,900 kWh/year across main house and one-bedroom annex
Export limit: 3.68 kW under G98
Expected generation: Approximately 7,000 kWh/year
Quoted price: £12,750
Installer: Local – MCS certified
Included: Panels, batteries, inverter, Renusol mounting system, wiring, isolators/meters, installation, commissioning, MCS certification, G98 application and a five-year insurance-backed workmanship warranty. I am confirming whether all roof access and bird-proofing are included.
Tariff used in quote: No specific tariff modelled. I’m currently on Utility Warehouse Value but am likely to move to an Octopus tariff that works better with solar and battery storage. The installer has suggested charging the batteries at around 7p/kWh overnight during winter/low-solar periods.
EV: No, although likely within the next three to five years
ASHP: No immediate plans

The installer estimates roughly 7,000 kWh/year from the 8.64 kWp array. His rationale for using a 3.68 kW inverter is that the south-east and north-west roofs will generate at different levels and times during the day. The system would supply the house and annex first, with excess generation directed to the batteries.

My main questions are whether £12,750 is competitive, whether 20 kWh of battery capacity is sensible for annual consumption of around 6,800 kWh, and whether the 3.68 kW inverter is appropriately sized for an 8.64 kWp array across the two orientations.

I also understand that the likely EcoFlow inverter can accept up to approximately 9.68 kWp of solar. If the roof layout allows it, would there be merit in adding another two 480W panels, taking the array to 9.6 kWp, or would the additional generation mostly be lost through clipping?
