A solar generator usually combines a portable battery power station with compatible solar panels. The battery stores energy; its electronics supply connected devices; the panels replenish the battery when conditions and equipment allow. The useful comparison is how much energy you can use, how much power your devices need, and how you will recharge.
This guide is for U.S. households comparing portable power for individual devices, travel or a defined backup need. Solar Survey AI provides survey and inspection services. We do not sell these power stations or present hands-on equipment tests here.
Capacity, output and solar input do different jobs
Watts (W) describe power. Watt-hours (Wh) describe energy. A constant 100 W load uses 100 Wh in one hour. A battery capacity rating is not the same as usable energy delivered to an appliance: conversion, operating settings, temperature, battery condition and the load itself can affect what is available.
Check continuous output, starting requirements and the limit shared by the outlets before estimating runtime. A device can exceed the power limit even when plenty of battery energy remains. A surge or special operating-mode figure should not be substituted for the normal continuous output rating.
Read the exact model’s specifications
These five manufacturer examples illustrate the units. They are not a ranking, purchasing recommendation or independent performance test. Specifications were checked October 15, 2026; confirm the exact U.S. model, manual, bundle and current availability with the manufacturer.
Swipe or scroll the table sideways to compare all columns.
| Model and source | Battery capacity | Total AC output | Maximum solar input |
|---|---|---|---|
| Jackery Explorer 2000 v2 / JE-2000D | 2,042 Wh | 2,200 W total across three AC ports | 400 W with the specified dual-port configuration; 200 W for one port |
| BLUETTI AC180 | 1,152 Wh | 1,800 W total across four AC outlets | 500 W maximum |
| EcoFlow DELTA 2 (U.S./Canada manual) | 1,024 Wh | 1,800 W total; U.S./Canada AC rating is 120 V | 500 W maximum; 11–60 V, 15 A maximum |
| EcoFlow DELTA 3 (base station) | 1,024 Wh | 1,800 W total across six AC outlets | 500 W maximum; specified solar input is 11–60 V |
| Anker SOLIX C1000 Gen 2 | 1,024 Wh | 2,000 W total AC rated output | 600 W maximum; 60 V maximum solar input |
For example, three Jackery AC outlets do not provide three times the station’s 2,200 W total. The BLUETTI AC180 and AC180P have different capacity ratings; do not transfer a specification between similar model names. An input maximum is an equipment limit, not a promise that the panels will deliver that power throughout the day.
The EcoFlow DELTA 3 example uses the base station’s 1,024 Wh capacity and normal 1,800 W AC rating. Its separately listed 2,200 W X-Boost figure is not substituted for that normal output. DELTA 2, DELTA 3 and DELTA 3 Plus are different model names; confirm the exact name on the unit and its documentation before comparing ratings.
EcoFlow DELTA 2: check the exact manual
The DELTA 2 manual provides a separate reference for this model. During our October 15, 2026 review, its old U.S. store URL redirected to DELTA 3. That redirect does not make the two models interchangeable or establish DELTA 2 stock availability. The DELTA 2 manual lists a 2,700 W surge and a separate 2,200 W U.S./Canada X-Boost figure; neither replaces its normal 1,800 W total AC rating. Match the model and regional specifications before comparing compatible equipment.
The Anker SOLIX C1000 Gen 2 specifications illustrate why capacity and output need separate rows: it and the DELTA 3 list 1,024 Wh, while their normal AC ratings are 2,000 W and 1,800 W respectively. Matching battery-capacity labels do not establish matching usable energy, runtime or load compatibility. Anker separately lists a 3,000 W peak figure; that is not substituted for its 2,000 W normal rating. Confirm the exact generation and regional model, panel voltage and current limits, cables and bundle contents in the applicable documentation before choosing equipment.
- Define the devices. Record running watts, starting requirements, hours of use and which devices overlap.
- Check usable energy. Look for a relevant manufacturer runtime method or a measurement under comparable settings and loads. Keep nameplate capacity separate.
- Check every connection. Confirm output voltage, outlet type, shared power limits, panel voltage/current limits and required cables.
- Read the bundle. A station-only listing and a station-plus-panels kit are different purchases. Compare the complete contents.
- Plan operation. Review weight, placement, weather exposure, operating temperatures, charging methods and the actual warranty.
How long could a solar generator run your devices?
For a constant load, an illustrative runtime is usable energy divided by power demand. Use an assumed usable energy at the output, after the losses and reserve you have allowed for. This worksheet does not convert a manufacturer’s battery rating into measured usable energy.
Check the power limit first. The arithmetic below does not check whether your equipment can start or run the selected load. For devices that cycle on and off, a single watt figure may not represent their energy use over time.
Swipe or scroll the table sideways to compare all columns.
| Constant total load | Arithmetic runtime | What the number does not establish |
|---|---|---|
| 50 W | 32 hours | Actual standby use or device compatibility |
| 100 W | 16 hours | Weather, battery condition or a critical-load guarantee |
| 800 W | 2 hours | Starting capability or sufficient continuous output |
If the load doubles from 100 W to 200 W while the usable-energy assumption stays at 1,600 Wh, the result falls from 16 to 8 hours. That relationship helps compare a load plan; it does not verify real-world battery performance. Keep essential-use planning separate from this educational tool.
Build a daily solar-generator load plan
Different devices may run for different lengths of time. List each device’s assumed electrical draw and powered hours, then choose which running loads overlap in one scenario. Keep the energy total in watt-hours separate from the selected running power in watts.
Every starting value below is invented for teaching, not an appliance rating, product test or recommendation. For cycling devices, one running-watt figure and clock hours may be misleading: use a relevant measured energy record or manufacturer method. Check starting requirements separately; this planner does not calculate them.
Keep these unresolved checks with the record
- Record the source, mode and measurement period for every watt or energy figure. Replace the invented values with relevant evidence.
- Verify starting demand, voltage, frequency, outlet and shared-port limits, and the exact station’s operating instructions independently.
- Confirm whether losses, reserve and station self-consumption are already represented in your usable-energy assumption; do not count them twice.
- Keep charging and a different overlap scenario as separate comparisons. A daily energy total does not show when a battery will empty or refill.

Solar charging: match the panel and the input
Start with the exact station’s panel-input instructions. Connector shape alone does not establish compatibility. Check the permitted voltage range, current and power limits, polarity, adapters and permitted panel configurations. Use the manufacturer’s instructions for connections rather than extrapolating from a panel’s advertised wattage.
Jackery’s linked specification, for example, lists a 16–60 V solar input range and different single- and dual-port limits. Those details illustrate why a nominal panel-watt total is not enough to approve a connection. Follow the model-specific rules rather than applying this example to another station.
The worksheet’s 8-hour replacement example means eight equivalent hours at an assumed constant 200 W input. It does not mean eight clock hours outdoors will recharge a real battery. Sun angle, shade, weather, panel orientation, input limits and charging behavior affect the result; loads running during charging also consume energy.
Portable power and a home backup system serve different needs
Running individual compatible devices from a portable station is different from connecting backup equipment to household circuits. DOE’s solar resilience overview explains that ordinary grid-connected solar generally shuts down during a grid outage and that backup requires suitable equipment and configuration. For a home project, compare the proposed circuits and operating design with the responsible installer. This guide does not provide house-wiring instructions.
For permanent solar planning, use our home solar system and sizing guide and roof, shade and battery questions. A portable-generator runtime illustration does not size a rooftop array or establish whole-home backup.
Solar generator questions
What is the difference between a solar generator and a portable power station?
In this guide, a solar generator means a portable battery station used with compatible solar panels. A power-station-only purchase may not include panels or every required connection. Check the exact bundle.
Can a solar generator power a whole house?
Do not infer whole-house backup from a capacity number. Check simultaneous power, starting requirements, usable energy, intended circuits and the approved connection design. The worksheet only illustrates constant-load energy arithmetic.
Which solar generator is best?
Start with your devices, energy needs, charging conditions and exact equipment limits. This guide compares published units and provides a worksheet; it does not rank products or report hands-on tests.
Does a 400 W panel always charge at 400 W?
No. A panel rating and a station input limit do not guarantee delivered charging power. Conditions, compatibility and charging behavior affect the actual result.
Does the runtime worksheet store my inputs?
The calculation runs locally in your browser without sending the worksheet values to a server. It does not need an address, email or equipment account. General site analytics are described in the privacy policy.
Match the next step to your power plan
Use the worksheet to document assumptions before discussing a portable station with its manufacturer. If you are considering permanent solar for your home, continue with the system-planning guide and compare a complete installation proposal.
