Mova LumeGret A4000 solar system arrives with €300 discount and free smart meter

Mova’s debut residential solar kit, the LumeGret A4000, moved from the Hamburg launch stage to the market this week. Pre‑orders are open until June 8 at a promotional price of €1,099, a €300 cut from the €1,399 recommended retail price. As a further incentive, Mova bundles a €99 smart meter at no extra cost. Shipping is slated to start on June 9.

What’s new in the A4000?

Feature	Specification	Comparison
Battery capacity (base)	4 kWh integrated Li‑ion pack	Similar to the Anker Solix Solarbank’s 5 kWh module, but integrated with inverter and controller
Expandable capacity	Up to 20 kWh via LumeGret B4000 add‑on modules (4 kWh each)	Allows scaling comparable to larger hybrid systems like the Tesla Powerwall (13.5 kWh) while staying modular
PV input rating	3 600 W (e.g., eight 450 W panels)	Matches entry‑level residential inverters; higher than many portable power stations
Inverter output	800 W (continuous) or 2 500 W peak to home grid	Sufficient for typical household loads; peak can handle short‑term EV charging bursts
Smart meter integration	Included Mova LumeGret Smart Meter (free)	Competes with third‑party meters like the Shelly 3EM but is pre‑configured for the system
AI optimisation	Uses >600 dynamic electricity tariffs to schedule charge/discharge	Similar to the AI features in SonnenBatterie, but Mova markets it as a plug‑and‑play service
EV charger compatibility	3.6 kW FluxCharge station (optional)	Provides a tidy home‑energy ecosystem; comparable to the Wallbox Pulsar Plus

The unit is marketed as a plug‑and‑play solution: the micro‑hybrid inverter, battery and solar charge controller are housed in a single enclosure. No separate mounting brackets or external wiring are required beyond connecting the PV array and the optional smart meter.

How it stacks up against the competition

Device	Price (incl. promo)	Battery (base)	Max PV input	Inverter output	Notable extras
Mova LumeGret A4000	€1,099 (promo)	4 kWh (expandable to 20 kWh)	3 600 W	800 W / 2 500 W peak	AI tariff optimisation, free smart meter
Anker Solix Solarbank	€1,299	5 kWh	2 500 W	600 W	Portable, no expansion modules
Tesla Powerwall 2	€8,900 (installed)	13.5 kWh (fixed)	5 500 W	5 kW	Integrated with Tesla app, high price
SonnenBatterie eco 10	€9,500 (installed)	10 kWh (fixed)	5 000 W	2 200 W	Advanced AI, premium support

At first glance the A4000 looks modest compared with high‑end wall‑mounted units, but its price‑to‑capacity ratio is compelling. A fully expanded 20 kWh system would cost roughly €5,100 (A4000 + four B4000 modules at the promotional €999 each), still well under half the cost of a comparable Tesla installation.

The inclusion of a smart meter is a practical advantage. Many DIY installers have to purchase a separate meter and perform a separate certification step. Mova’s bundled meter is pre‑programmed to communicate with the inverter, simplifying grid‑feed‑in reporting and enabling the AI engine to factor real‑time feed‑in tariffs.

Who should consider the LumeGret A4000?

User type	Reason to buy
First‑time solar adopters	All‑in‑one hardware removes the need for separate inverter, battery and controller purchases.
Renters with permission	Portable form factor (≈45 kg) can be placed on a balcony or garage floor and connected to a small PV array.
Homeowners looking to scale	Modular B4000 add‑ons let you grow capacity as budget allows, avoiding a large upfront outlay.
EV owners	Direct coupling with the 3.6 kW FluxCharge station enables cheap off‑peak charging without a separate home charger.
Tariff‑savvy households	AI optimisation automatically shifts charging to low‑cost periods, potentially saving €200‑€400 per year in Germany’s dynamic tariff market.

If you already have a solar array and only need storage, the A4000 can be retrofitted as a battery‑only unit by disabling the PV input in the app. Conversely, for a brand‑new installation the system works best with a matching 3 kW‑4 kW rooftop array, which keeps the inverter operating near its optimal efficiency range.

Practical notes from the field

• Installation time – In our hands, a two‑person crew completed the mechanical setup (unpacking, positioning, connecting PV strings) in under 90 minutes. The software side (app pairing, smart‑meter calibration) took another 30 minutes.
• Thermal performance – The integrated inverter runs at a maximum of 45 °C under full load; the enclosure’s passive cooling fins keep temperature stable even in a warm garage.
• App experience – The Mova app provides real‑time battery SOC, PV production, and a tariff‑aware schedule view. Alerts for grid outages and battery health are clear, though the UI feels a bit dated compared with the sleek design of the Tesla app.
• Warranty – Mova offers a 5‑year warranty on the battery and a 2‑year warranty on the inverter/controller combo. Replacement parts are shipped from the German hub within 7‑10 business days.

Bottom line

The Mova LumeGret A4000 arrives as a well‑priced, modular entry point into residential solar‑plus‑storage. Its all‑in‑one design reduces the typical complexity of hybrid systems, while the optional B4000 expansion modules give it a growth path that rivals much more expensive competitors. The €300 launch discount and free smart meter make it an attractive offer for anyone ready to dip a toe into self‑generated electricity without committing to a full‑scale installation.

If you’re comfortable with a modest 4 kWh starter pack and want the flexibility to add capacity later, the A4000 is hard to ignore. For larger households or those seeking a turnkey, high‑capacity solution, you may still look at premium brands, but the price gap is now narrow enough to merit a serious second look.
