The $1000 Solar Generator Setups

I built two $1000 solar generator setups for testing. The first uses a Bluetti AC180 power station paired with two 200W solar panels, costing approximately $930. The second features an EcoFlow Delta 3 Plus power station, along with four 100W panels, which came to around $1010. Both setups were easy to assemble, requiring no tools.

The Bluetti AC180 setup's simplicity was a plus, with straightforward panel and cable connections. The EcoFlow Delta 3 Plus, while pricier, offered dual solar charging ports—a significant advantage for handling multiple panels.

Solar Panel Connection and Charging

Connecting the Bluetti's two 200W panels in series produced a combined 46V output, safely within the power station's 12V-60V solar input range. This setup charged at approximately 261W, with an estimated 2.1 hours to full charge (in ideal conditions).

The EcoFlow Delta 3 Plus's dual charging ports allowed for a more efficient setup with four 100W panels. Initially, connecting two pairs in series and then in parallel yielded a 290W charging rate. Further optimizing this using series-parallel wiring maximized the Delta 3 Plus's charging capability.

Real-World Usage and Runtime Tests

A one-hour charging test with the Bluetti setup, hampered by partial shade, resulted in a modest 11% increase in the power station's charge. The initial estimate of 3 hours to fully charge the power station was likely accurate in full sun.

Numerous devices and appliances were tested to determine runtimes for both setups, factoring in estimates for fridge usage. Adding solar input significantly increased runtimes, more than doubling the runtime for a space heater from under 2 hours to 4.1 hours with a 300W solar input.

Estimating Solar Power Output and Runtime

A rule of thumb suggests 100W of solar panels produce 300-500Wh per day. With 400W of panels, this equates to 1200-2000Wh per day under ideal conditions. Cloudy weather significantly reduces this, emphasizing the importance of battery capacity for longer runtimes without solar input.

The power stations' runtimes varied depending on the device. For example, the space heater’s runtime was significantly improved with solar panel input. This illustrates that using a solar generator is dependent on sufficient sunlight to recharge the battery over time.

Bluetti AC180 vs. EcoFlow Delta 3 Plus: A Comparison

Both power stations offer 1800W continuous AC output, capable of powering most household appliances. However, the EcoFlow Delta 3 Plus, despite costing $200 more, has slightly less battery capacity (1260Wh vs. 1152Wh).

Efficiency testing revealed that the Delta 3 Plus boasts slightly better AC efficiency (88.1%) than the Bluetti AC180 (84.8%). The Delta 3 Plus also features faster charging (approximately 12 minutes faster from 0 to 100%), but self-consumption was quite similar between both units.

EcoFlow Delta 3 Plus's Unique Features

The EcoFlow Delta 3 Plus's key advantage lies in its app-controlled operating modes. Time-of-use mode optimizes charging based on electricity rates, potentially saving money. Self-powered mode prioritizes solar charging, creating a grid-tied system-like setup and ensuring battery backup for use during periods of poor solar output.

These features are geared towards daily usage, transforming a solar generator setup from occasional use into a daily, money-saving tool for reducing reliance on the power grid and utilizing renewable energy. This makes the Delta 3 Plus a much more versatile device.

Conclusion: Which $1000 Solar Generator Setup Is Best?

Both the Bluetti AC180 and EcoFlow Delta 3 Plus provide excellent power for their price points. The Bluetti AC180 offers slightly more battery capacity at a lower price, making it great for basic needs. The EcoFlow Delta 3 Plus, however, justifies its higher price with superior charging capabilities, greater efficiency, and unique app-controlled modes for more sophisticated usage scenarios.

Ultimately, the best choice depends on individual needs and budget. For those seeking a simple, cost-effective solution, the Bluetti AC180 is excellent. If advanced features and smart energy management are prioritized, the extra cost of the EcoFlow Delta 3 Plus is worthwhile. The EcoFlow’s additional features make it a more versatile and useful option for daily use.
