How to size a solar power station
A solar power station (portable power station) keeps essentials running through a Philippine brownout without touching your home's wiring. The hard part isn't finding one — it's picking the right size. Three steps get you there.
Step 1 — do a power audit
List what you actually want to keep running, and add up the watts. Typical Philippine household loads:
| Appliance | Typical draw |
|---|---|
| Wi-Fi router | 10–30W |
| Laptop | ~60W |
| Electric fan | ~35W |
| 3 LED lights | ~15W |
| Bar fridge | 100–150W |
| CPAP (no humidifier, low setting) | runs most of the night |
Sum your target appliances' watts, then size a unit rated about 20–30% above that total.
Step 2 — estimate runtime
Rule of thumb: runtime (hours) ≈ capacity (Wh) ÷ load (W), minus roughly 15% for inverter losses. Some reference points:
- River-class (230–500Wh): 1–2 nights of CPAP (no humidifier); router + lights + fan + phone for about 4–8 hours.
- River 2 Pro / River 3 Max Plus (700–900Wh): fridge + fan + router + lights for about 8–12 hours.
- Delta-class (1–2kWh): roughly 9 hours at ~95W continuous load — fridge and essentials overnight, or a full WFH day.
- Delta 2/3 Max (2–2.4kWh, expandable to 6kWh): multi-appliance coverage for a full-day outage — SME or home-office use.
- Delta Pro-class (3.6kWh+): whole-room or small-aircon loads, multi-day typhoon coverage when paired with a 200–400W solar panel.
Step 3 — match your class
Line your outage pattern and appliances up against the three classes, then jump to a top pick.
Mid · Delta-classMost homes
Multi-hour to a full day
Fridge, fan, lights, and WFH gear running at once. The right size for most Philippine homes.

Large · Delta Pro-class
Multiple days
Bigger homes, a small aircon or freezer, and multi-day typhoon resilience. Pairs with solar as a home battery.

Frequently asked questions
What is a solar power station, exactly?
It is a portable battery pack with a built-in inverter and charge controller — you charge it from a wall outlet, car, or a solar panel, then plug appliances directly into it. It is separate from a rooftop solar installation and does not require any wiring changes to your home.
How do I size a unit for my home?
Do a quick power audit: list every appliance you want to keep running during an outage, note its wattage, and add them up. Size a unit rated roughly 20–30% above that total continuous wattage, then check its Wh capacity against how many hours you need to cover.
How long will a given unit actually last?
Roughly, runtime hours = capacity (Wh) ÷ your total load (W), minus about 15% for inverter losses. A 1,000Wh unit running a 95W load lasts about 9 hours. See the runtime table below for common load combinations.
Can I recharge it with solar during a multi-day outage?
Yes — pair a portable solar panel with your unit. A 100W panel recharges a small River-class unit (around 256Wh) in roughly 3–5 hours of good sun; a 200–400W panel is a better match for Delta-class units needing a daily top-up.
Is a bigger unit always better?
Not if you are overpaying for capacity you will not use. Match the unit to your actual outage pattern: short, occasional brownouts favor a River-class unit; families running a fridge and WFH setup through longer outages get better cost-to-runtime from Delta-class; only go Delta Pro-class if you need whole-room or multi-day coverage.
