Growatt INFINITY 2000 Pro

The Growatt INFINITY 2000 Pro is a 2,048 Wh LiFePO4 station with 2,400 W of output, 4,000 declared cycles, a 15 ms switchover and expansion to 6,144 Wh. The spec sheet reads well. The problem is what it leaves out: weight and solar input, two figures you need before buying. We have not run this unit ourselves: the data comes from the official Amazon listing, checked on September 26, 2026, and the math is ours.

Quick verdict

Growatt INFINITY 2000 Pro

2,048 Wh · 2,400 W

8.5/10 · WilderWatt score

The INFINITY 2000 Pro covers the basics of a 2 kWh backup station. It stores 2,048 Wh in LiFePO4 cells rated for 4,000+ cycles, a figure several rivals do not publish. Its 2,400 W of output runs a microwave and a coffee maker together, and the 15 ms switchover keeps a fridge and router running through a grid drop. Expansion to 6,144 Wh triples capacity, and the warranty is 5 years. The missing data is the catch. Without a published weight or solar input, you cannot judge portability or size panels from the listing. Check the manual first.

Pros

• 2,048 Wh LiFePO4 with 4,000 declared cycles
• 2,400 W of output and a 15 ms EPS switchover
• Expandable to 6,144 Wh, 5-year warranty

Cons

• Weight not published in the US listing
• No published solar input or surge figure

Best for

Home backup buyers who want declared cycle life and moderate expansion

Skip it if

Anyone planning a solar array or who needs to know the weight before buying

How long does it run your devices?

Plan on about 1,741 usable watt-hours. We apply 0.85 for inverter and conversion losses: 2,048 × 0.85 = 1,741 Wh.

Load (typical draw)	Math	Approximate runtime
Full-size fridge, 60 W average	1,741 ÷ 60	29 hours
Fridge + router + LED lights, 95 W	1,741 ÷ 95	18.3 hours
CPAP without humidifier, 40 W	1,741 ÷ 40	43.5 hours
Window AC unit, 500 W	1,741 ÷ 500	3.5 hours
Microwave, 1,200 W	1,741 ÷ 1,200	about 87 minutes

That is most of a day of essentials. For your own appliance list, use the solar calculator.

What can 2,400 W run?

One large 120 V appliance, or two mid-size ones together. 2,400 W is 20 A of total output. A 1,200 W microwave plus a 1,000 W coffee maker is 2,200 W, within the limit.

The standalone listing does not publish a surge figure, though the listing for the kit with a 200 W panel states 3,100 W. Motor loads such as sump pumps and compressors spike at start-up, so check your appliance’s starting watts and confirm the surge rating with Growatt before relying on it for a pump.

Is the 15 ms EPS a real UPS?

It works like one for most home loads. Growatt calls it EPS, for emergency power supply, and declares a 15 ms switchover.

Fridges, routers, lights and laptops ride through that easily. For desktop PCs and NAS drives, 15 ms usually works, but 10 ms units give more margin. The Bluetti AC200PL and EcoFlow DELTA 3 Max Plus both declare 10 ms. Our home backup picks compare this spec directly.

How does it charge from solar?

The US listing does not state a maximum solar input. So we can only show how many panel watts a full refill takes, using capacity ÷ (panel watts × 0.75):

• 200 W of panels: 2,048 ÷ 150 = 13.7 peak sun hours, about three summer days.
• 400 W of panels: 2,048 ÷ 300 = 6.8 peak sun hours.
• 800 W of panels: 2,048 ÷ 600 = 3.4 peak sun hours.

Growatt also sells the station bundled with a 200 W panel; we compare it in our best solar generators. One 200 W panel is a trickle for a 2 kWh battery, so plan on more if solar matters to you.

How far can you expand it?

Up to 6,144 Wh, three times the built-in capacity, with 2 expansion batteries. Fully expanded, usable energy is 6,144 × 0.85 = 5,222 Wh.

On a 95 W essentials load, that is 5,222 ÷ 95 = 55 hours, about 2.3 days. That is less headroom than the EcoFlow DELTA 3 Max Plus (10,000 Wh) or the Bluetti AC200PL (8,448 Wh), but enough for most storm outages.

What does the listing leave out?

Weight, solar input, surge rating, outlet count and AC charging time. Each matters in practice.

• Weight: you cannot compare portability, and our score cannot credit energy density.
• Solar input: you cannot size panels safely.
• Surge: motor loads are a guess.

Our review method only scores what the manufacturer declares, so missing data costs points.

• Bluetti AC200PL: 2,304 Wh, 1,200 W solar input, 10 ms UPS and expansion to 8,448 Wh. The catch is 32.7 kg. Full matchup in Bluetti AC200PL vs Growatt INFINITY 2000 Pro.
• Jackery Explorer 2000 v2: 2,042 Wh at 17.9 kg with a 102-minute emergency wall charge. The catch is no expansion and no published solar input. Read our Jackery Explorer 2000 v2 review.

Who should buy the Growatt INFINITY 2000 Pro?

Buyers who want declared cycle life and moderate expansion, and who will check the manual for the rest.

Buy it if you:

• Want a 2 kWh backup station with 4,000 declared cycles.
• Need 2,400 W and some room to grow.

Skip it if you:

• Plan to carry it and need to know the weight.
• Want to size a solar array from published limits.
