How to Read This Data
Each kit record shows advertised price, real build cost, panel input wattage, storage in Wh, inverter wattage, and completeness score. For portable power stations, real build cost equals the advertised price -- these are integrated units with battery, charge controller, and inverter built in. The completeness gap between 57% and 86% reflects whether solar panels are bundled into the purchase, not missing electronics.
Panel input (W) is the maximum wattage the station's MPPT charge controller will accept from connected solar panels. Connecting panels above this limit does not damage the unit -- the controller caps input at its rated maximum.
Storage (Wh) determines how long equipment runs. Panel input wattage determines how fast the station recharges. A DIY portable solar setup requires both numbers to be matched -- oversizing panels relative to the station's input limit wastes money; undersizing them extends recharge time past practical limits.

Portable Solar Systems by Price Tier
Entry Tier: Under $400
The EcoFlow RIVER 3 at $199 carries 245Wh of LiFePO4 storage with battery, charge controller, and inverter integrated. Completeness is 57% -- no bundled solar panels, no hard mounting hardware. The MC4 solar input port accepts compatible folding panels. Cost per Wh at this tier: $0.81/Wh. Entry price trades storage efficiency for portability and low upfront cost.
The Bluetti AC50P bundle at $359 changes the equation. It includes a 200W matched panel array, 504Wh of storage, a 700W inverter, and built-in MPPT. Completeness is 86%. Cost per Wh: $0.71/Wh. Solar recharge at 200W input in full sun: approximately 3 hours (504Wh / (200W x 0.85) = 2.96 hours).
PREMIUM 50 AC50P 504Wh/700W
Mid Tier: $400-$800
The Anker SOLIX C1000 Gen2 at $449 carries 1,024Wh of storage, a 2,000W inverter, and accepts up to 600W of solar input via its MPPT controller. Completeness is 86%. Cost per Wh: $0.44/Wh -- a $0.37/Wh improvement over the RIVER 3 entry option. At 600W solar input in full sun, solar recharge runs approximately 2 hours (1,024Wh / (600W x 0.85) = 2.01 hours). Anker rates AC recharge at 49 minutes.
SOLIX C1000 Gen2 1,024Wh/2,000W + Main Unit Only
The Bluetti AC70P bundle at $499 pairs 500W of panels with 864Wh of storage and a 1,000W inverter. Cost per Wh: $0.58/Wh. Solar recharge at 500W: approximately 2 hours (864Wh / (500W x 0.85) = 2.03 hours).
The Bluetti AC180P at $699 bundles a 500W panel array with 1,440Wh of storage and a 1,800W inverter. Completeness is 86%. Cost per Wh: $0.49/Wh. Solar recharge at 500W: approximately 3.4 hours (1,440Wh / (500W x 0.85) = 3.39 hours).
Premium 150 AC180P + Main Unit Only
The EcoFlow DELTA 3 Plus at $699 carries 1,024Wh of storage and an 800W inverter. Completeness is 71%: the unit ships without solar panels. Add compatible folding panels via the MC4 input port to enable solar recharging.

Upper Tier: $800+
The Anker SOLIX C2000 Gen2 at $799 carries 2,048Wh and a 2,400W inverter. No bundled panels -- completeness is 71%. Cost per Wh: $0.39/Wh -- the lowest $/Wh among portable options in the database. This is the same rate as the EcoFlow DELTA 3 Max at the same price point. Add compatible folding panels to enable solar recharging.
The New Use Energy SunCase 605 at $980 is the outlier: a briefcase-form-factor system with 400W of integrated folding panels and 540Wh of storage. Completeness is 86%. Cost per Wh: $1.81/Wh -- the highest in the database at this capacity. The premium reflects ruggedized hardcase construction, not storage density.

Matching Panel Watts to Station Capacity
The central sizing decision for any DIY portable solar setup is matching panel wattage to station input capacity. The formula for solar recharge time:
Hours = Storage (Wh) / (Panel W x 0.85)
The 0.85 factor accounts for MPPT conversion losses and real-world irradiance below the panel's rated output. In practice, folding panels in full sun deliver 70-90% of their rated output; 0.85 is a conservative midpoint.
| Station | Panel Input | Solar Recharge Time |
|---|---|---|
| Bluetti AC50P (504Wh) | 200W | ~3.0 hours |
| Bluetti AC70P (864Wh) | 500W | ~2.0 hours |
| Anker SOLIX C1000 Gen2 (1,024Wh) | 600W | ~2.0 hours |
| Bluetti AC180P (1,440Wh) | 500W | ~3.4 hours |
A 3-hour recharge window within a 4-5 peak-sun-hour day leaves margin for partial cloud cover. Stations that accept 600W or more input (like the Anker C1000 Gen2) can complete a full recharge in 2 hours -- practical even on shorter or partially overcast solar days.
MPPT Voltage Compatibility
Every portable station in the database uses a built-in MPPT charge controller. Before connecting a third-party panel, verify three specs against the station's manual:
- VMP range -- the panel's maximum power voltage must fall within the station's MPPT input voltage window (typically 11V-60V for portable units)
- Short-circuit current (ISC) -- must not exceed the station's rated solar input amperage
- Connector type -- most portable stations use MC4 or XT60 connectors; use the manufacturer's adapter cable for third-party panels
Folding panels from EcoFlow, Anker, Bluetti, and Goal Zero ship with pre-wired connectors matched to their own stations. Cross-brand connections work with a compatible MC4 adapter, provided the voltage and current specs align.

Capacity by Use Case
The table below shows runtime before a solar recharge is needed. All figures assume 80% depth of discharge on LiFePO4 cells.
| Device | Wh per Use | 245Wh | 504Wh | 1,024Wh | 1,440Wh |
|---|---|---|---|---|---|
| Phone (full charge) | 15Wh | 13 charges | 27 charges | 55 charges | 77 charges |
| Laptop | 60Wh | 3 charges | 7 charges | 14 charges | 19 charges |
| CPAP (8h, no humidifier) | 36Wh | 5 nights | 11 nights | 23 nights | 32 nights |
| Mini fridge (12V, 50W avg) | 400Wh/day | 0.5 days | 1.0 days | 2.0 days | 2.9 days |
| LED lights (10W x 6h) | 60Wh | 3 nights | 7 nights | 14 nights | 19 nights |
A 245Wh entry station handles phones, a laptop, and a CPAP for a multi-night camping trip when paired with a daily solar recharge. A 1,024Wh station runs a portable fridge for 2 days between full solar recharges -- practical for a weekend basecamp setup without hooking into shore power.
