Three LiFePO4 solar generators between $899 and $1,199. The cheapest is the best fit for most homes; the biggest has 76% more capacity for $300 more. Here’s the full breakdown.
The mid-range solar generator market sits between about $900 and $1,200. That’s where most first-time buyers land — enough power for real backup (fridge, lights, router, laptops) without the $2,000+ commitment of a whole-home system.
These three units define the tier. They share the same battery chemistry (LiFePO4), similar port layouts, and a price tag that puts them head-to-head. But the differences are significant enough to matter.
Let’s break them down one at a time, then stack them side by side.
The OSCAL PowerMax 3600 SE has the biggest numbers here. 3,600Wh of LiFePO4 capacity is 76% more energy than either competitor, and 3,600W continuous output (4,500W surge) runs a fridge, a microwave or a power tool. Its 2,400W solar input is double the BLUETTI’s, and OSCAL rates a full solar recharge at about 2.25 hours in ideal sun. At $1,199 it costs $300 more than the AC200L, but works out to $0.33 per watt-hour, the lowest of the three.
Battery: LiFePO4, 3,500+ cycles to 80% — roughly 10 years of daily use.
Ports: 14 outlets in total, including 2x USB-C (100W), 4x USB-A and an Anderson DC port.
Features: 5–8ms UPS switchover, Wi-Fi and Bluetooth app control, built-in LED light, 5-year warranty. OSCAL doesn’t list expansion batteries for the 3600 SE.
The BLUETTI AC200L is the one we’d point most homeowners to. At $899 it’s the cheapest of the three, it matches the DELTA 2 Max on capacity and output, and it wins where long-term owners care most: ecosystem depth, build quality reputation, and expansion flexibility. The B210 and B300 expansion batteries give you a growth path from 2,048Wh all the way to 8,192Wh+ without buying a new unit.
Battery: LiFePO4, 3,000+ cycles to 80%.
Ports: 4x AC, 2x USB-A, 2x USB-C (100W), 1x 12V car port, 1x wireless charging pad (15W).
Features: UPS mode, Bluetooth + Wi-Fi app control, dual charging (AC + solar simultaneously), wireless charging pad.
The EcoFlow DELTA 2 Max is the lightest unit here at 51 lbs — 47 lbs lighter than the OSCAL. It also has the fastest wall charging in the industry: X-Stream technology gets you from 0 to 80% in just 43 minutes. If you move your generator between locations (RV, campsite, home) or need rapid recharging before a storm hits, EcoFlow is the speed play.
Battery: LiFePO4, 3,000+ cycles to 80%.
Ports: 6x AC, 4x USB-A, 2x USB-C (100W), 1x 12V car port.
Features: UPS mode, Wi-Fi + Bluetooth app, X-Stream fast charging, X-Boost (handles devices up to 3,400W), expandable with DELTA 2 Max Extra Battery.

At $899, the AC200L is the lowest price here for the same 2,048Wh and 2,400W as the DELTA 2 Max, and it can grow with expansion batteries. For a fridge, lights, router and laptops through an overnight outage, it covers you for the least money.
At $0.33/Wh, the OSCAL still delivers the most energy per dollar: 3,600Wh for $1,199, against $0.44/Wh for the AC200L and $0.51/Wh for the DELTA 2 Max. The gap is smaller than it was with the old $699 PowerMax 3600, and you pay for it in weight (98 lbs).
BLUETTI’s expansion battery lineup is the deepest of these three brands. The B210, B300, and B300S give you flexible growth paths without replacing your base unit. Add a community with millions of units in the field, and you get the safest “bet on the brand” option in this tier.
At 51 lbs, the EcoFlow is 11 lbs lighter than the BLUETTI and 47 lbs lighter than the OSCAL. For RV users, campers, and anyone who moves their generator regularly, that weight difference matters every single time you pick it up.
2,400W of solar input is more than double the EcoFlow’s 1,000W and double the BLUETTI’s 1,200W. Off-grid users who depend on solar panels for recharging will fill the OSCAL fastest — critical during extended outages or remote camping.
X-Stream technology delivers 0–80% in 43 minutes from a wall outlet. When a storm warning drops and you need a full battery fast, EcoFlow’s charging speed is unmatched. The other two take roughly 2 hours for a full wall charge.
This comparison looks different than it did in September. The old PowerMax 3600 at $699 was a runaway value; its replacement, the PowerMax 3600 SE, is $1,199. It still has the biggest numbers — capacity, output, solar input — and the lowest cost per watt-hour ($0.33 vs. $0.44–$0.51), but it’s now the most expensive of the three up front, and the heaviest by far.
For most homes, the BLUETTI AC200L at $899 is the smarter buy: the lowest price, a proven brand, and expansion batteries when you need more. Choose the EcoFlow DELTA 2 Max ($1,049) if you move your unit a lot or need the fastest wall charging.
Choose the OSCAL PowerMax 3600 SE if you need 3.6kWh in one box and plenty of solar input, and you’re fine with a newer brand and a 98 lb unit that stays put.
Only if you need the extra capacity. At $1,199 it has the lowest cost per watt-hour ($0.33) and 3,600Wh in one unit, but it costs $300 more than the BLUETTI AC200L ($899), weighs 98 lbs, and OSCAL is a newer brand. If 2kWh covers your needs, the AC200L is the better value.
Best value for most homes: BLUETTI AC200L ($899, 2,048Wh, expandable). Most capacity per dollar: OSCAL PowerMax 3600 SE ($1,199, 3,600Wh). Best portability: EcoFlow DELTA 2 Max ($1,049, 51 lbs, 43-min fast charge). All three use LiFePO4 with 3,000+ cycle life. Prices as of October 31, 2026.
OSCAL: 2,400W (highest — OSCAL rates a full recharge at about 2.25 hours in ideal sun). BLUETTI: 1,200W (~2.5–3 hours). EcoFlow: 1,000W (~3–4 hours). Higher solar input means faster off-grid recharging, which matters most during extended outages and remote camping.
Essential circuits, yes — fridge, lights, Wi-Fi, phone chargers, laptops. Not a full house with central HVAC. The OSCAL at 3,600Wh runs essentials for 24–36 hours. The BLUETTI and EcoFlow at 2,048Wh cover 14–20 hours, and both take expansion batteries for longer backup. For whole-home HVAC backup, look at the EcoFlow DELTA Pro Ultra or BLUETTI Apex 300 class.
