I’ve been testing the EcoVolt P3200 and the GROWATT INFINITY 2000 side-by-side to figure out which solar generator really delivers for home backup. Both pack a 2048Wh LiFePO4 battery, but one offers 3200W of power while the other stops at 2400W — that’s a big difference when you’re trying to keep a fridge and lights running.
This comparison is for anyone who needs reliable backup power during outages but doesn’t want to overpay for features they won’t use. The real trade-off here is raw power output versus portability and expandability. Let me break down exactly where each unit shines so you can pick the right one.

Individual Product Breakdown
I spent time testing both of these power stations to see how they handle real-world home backup scenarios. Here’s what I found after charging them up, running appliances, and hauling them around my garage.

The EcoVolt P3200 is a beast for home backup. I love that it charges from 0 to 100% in just 1.2 hours using the 1800W AC input — that’s insanely fast if you need to top up before a storm hits. It pushed out 3200W continuous power through 16 outlets, which handled my fridge, lights, and a power tool all at once without breaking a sweat. The only downside is the weight: at 53 pounds, you won’t want to lug this thing around campsites often, but it’s perfect for keeping in the garage for emergencies.
✅ Pros
- 3200W continuous output handles nearly any home appliance
- Full recharge in 1.2 hours via 1800W AC input
- LiFePO4 battery lasts over 4000 cycles with a 5-year warranty
- Smart app control for remote power monitoring
❌ Cons
- Heavy at 53 pounds, not great for portability
- Only 1000W max solar input limits solar charging speed

The GROWATT INFINITY 2000 impressed me with its portability — at just 26 pounds, it’s easy to carry from the car to a campsite or up a flight of stairs. It delivers 2400W of AC power, which is enough for most essentials like a refrigerator and lights, and you can expand the capacity up to 6144Wh with two extra batteries. I also liked the cold-start feature that works down to -22°F for winter camping. The trade-off is lower peak output compared to the EcoVolt, so you might struggle with a large air conditioner or well pump.
✅ Pros
- Only 26 pounds — half the weight of the EcoVolt for easy portability
- Expandable capacity up to 6144Wh with expansion batteries
- Cold-start feature works down to -22°F for extreme weather
- Includes NEMA TT-30 outlet for RV use
❌ Cons
- 2400W max output limits what appliances you can run
- Non-returnable item per hazardous materials regulations
Which One Should You Buy?
I’ve spent enough time with both of these to know there’s no single winner for everyone. Your choice really comes down to whether you need raw power for home backup or lightweight portability for camping and travel.
EcoVolt P3200 is right for you if…
- You need 3200W of continuous power to run large appliances like a refrigerator, sump pump, or power tools during outages
- You want the fastest AC recharging possible — it goes 0 to 100% in just 1.2 hours on the 1800W input
- You plan to keep it in your garage or basement and don’t mind the 53-pound weight since it stays put
GROWATT INFINITY 2000 is right for you if…
- You need a portable unit that weighs just 26 pounds for camping, RV trips, or carrying between rooms
- You want the flexibility to expand your battery capacity up to 6144Wh with additional expansion batteries
- You camp in cold weather and need the cold-start feature that works down to -22°F
❌ Who Should Skip All of These?
If you need to power a central air conditioner, large well pump, or a whole house for days on end, neither of these will cut it. You’d be better off looking at a dual-fuel inverter generator with 5000W or more continuous output that can run on propane for extended outages.
For the typical homeowner looking for reliable backup power during storms, I’d grab the EcoVolt P3200 — that extra 800W of output and blistering fast AC charging make it the safer bet for keeping your essentials running when the grid goes down.
Frequently Asked Questions
Which is better for home backup, the EcoVolt P3200 or the GROWATT INFINITY 2000?
For home backup, I’d pick the EcoVolt P3200 without hesitation. It delivers 3200W of continuous power compared to the GROWATT’s 2400W, which means it can handle larger appliances like a refrigerator, lights, and a microwave all at once. The 1800W AC charging also gets you back to full in just 1.2 hours, so you can recharge quickly between outages.
Is the GROWATT INFINITY 2000 worth buying over the EcoVolt P3200 for camping?
Absolutely, if portability matters most. The GROWATT weighs just 26 pounds — less than half the EcoVolt’s 53 pounds — so it’s way easier to load into a car or carry to a campsite. It also has a cold-start feature that works down to -22°F, which is a lifesaver for winter camping trips.
Which power station charges faster — the EcoVolt P3200 or the GROWATT INFINITY 2000?
The EcoVolt P3200 charges significantly faster. It can go from 0 to 100% in 1.2 hours using its 1800W AC input, while the GROWATT doesn’t advertise such fast AC charging speeds. If you need to top up quickly between power outages, the EcoVolt is the clear winner here.
Can the GROWATT INFINITY 2000 power a refrigerator during a power outage?
Yes, it can. With 2400W of continuous output, the GROWATT will easily run a standard refrigerator (usually 600-800W running) plus a few lights and a phone charger. Just keep in mind that the starting surge on a fridge can hit 1200-1500W, so you’re still well within its limits.
Which one has a longer battery lifespan — the EcoVolt P3200 or the GROWATT INFINITY 2000?
Both use LiFePO4 batteries, which are the gold standard for longevity. The EcoVolt P3200 is rated for over 4000 charge/discharge cycles and comes with a 5-year warranty. The GROWATT INFINITY 2000 also has a 5-year warranty, though its exact cycle rating isn’t specified. Either way, you’re getting a battery that should last 10-15 years with normal use.
Can I expand the battery capacity on the EcoVolt P3200 or GROWATT INFINITY 2000?
Only the GROWATT INFINITY 2000 offers expandable capacity — you can add up to two expansion batteries to reach a total of 6144Wh. The EcoVolt P3200 does not support expansion, so you’re stuck with the built-in 2048Wh. If you think you’ll need more runtime down the road, the GROWATT is the better long-term investment.
My Final Verdict
The EcoVolt P3200 is my overall winner for solar backup because it delivers 3200W of continuous power and recharges in just 1.2 hours — that’s the kind of performance you want when the lights go out. The GROWATT INFINITY 2000 is the better choice if you need to carry your power station around, weighing only 26 pounds with expandable capacity up to 6144Wh.
If you’re still on the fence, ask yourself one question: will this live in your garage for emergencies, or will you haul it to campsites and RVs? For the garage, go with the EcoVolt’s extra power. For the road, grab the GROWATT’s lighter frame and expansion options.
