Home Use Buying Guide
Sizing for Your Actual Loads
For home backup use, the two loads that drive sizing are your refrigerator and any medical equipment (CPAP, oxygen concentrator). Everything else is secondary. Here’s a quick reference:
- Refrigerator (avg 75W continuous): needs ~600Wh per 8 hours
- CPAP without humidifier (30–50W): needs ~300–400Wh per night
- Window AC (500–1200W): needs 2–5kWh for 4–6 hours of operation
- Sump pump (750–1500W, intermittent): needs 200–600Wh over several hours
- Phones, laptops, lights (combined ~100W): needs 400–800Wh per day
Add those numbers up for your priority loads, multiply by 1.2 for inverter inefficiency, and that’s your minimum useful capacity. Most homeowners land in the 1–2kWh range for essentials-only backup, and 3–4kWh for comfort-level coverage.
Which Capacity Tier Is Right for You?
- Under 1kWh (AC70): Short outages (2–4 hours), devices and lights only, apartments or renters
- 1kWh (DELTA 3 Plus): Overnight essential backup — fridge + CPAP + device charging
- 2kWh (AC200L or Jackery 2000 Plus): 24-hour+ coverage — fridge, all devices, small AC or fan
- 4kWh (DELTA Pro 3): 48-hour+ coverage — full comfort backup, window AC, multi-day outages
Solar Panels for Home Recharging
For home backup, solar recharging is less about daily use and more about surviving extended grid outages. The goal is to generate enough each day to cover what you consume overnight. General guidelines:
- Running a fridge 24/7 consumes roughly 1.5–2kWh per day
- A 400W panel array produces ~1.5–2kWh on a good sun day (4–5 peak hours)
- To offset fridge + device charging + one hour of window AC: aim for 600–800W of panels
- Rigid rooftop-style panels (100–200W each) are most efficient; foldable panels work well for temporary setups
UPS Mode vs. Standard Mode
Most units in this guide include a UPS (uninterruptible power supply) mode that keeps the generator on standby, instantly switching to battery power when grid power drops. This is essential for sensitive electronics — routers, desktop computers, medical devices — that can’t tolerate even a brief power interruption. The AC70, DELTA 3 Plus, and Jackery 2000 Plus all include UPS mode. The AC200L does not — it requires a manual switch.
Frequently Asked Questions
Can a solar generator power an entire house?
No — not a whole house simultaneously. A typical home pulls 5,000–20,000W at peak, far beyond any portable solar generator’s inverter output. What these units do well is power essential circuits: a refrigerator, lights, phone charging, a window AC unit, and a CPAP or medical device. For whole-home backup, you’d need a stationary battery system (like Tesla Powerwall) or a large generator. For outages lasting hours to a day or two, a 2–4kWh solar generator handles the things that matter most.
How long will a solar generator run a refrigerator?
A standard refrigerator draws 100–200W while running and cycles on about 30–50% of the time, averaging 50–100W continuously. A 1024Wh unit like the DELTA 3 Plus will run it for roughly 8–12 hours. A 2048Wh unit like the AC200L or Jackery 2000 Plus runs it for 16–24 hours. The DELTA Pro 3 at 4096Wh can run it for 30–40+ hours — enough to cover a multi-day outage if you’re also solar charging during the day.
What’s the difference between a solar generator and a whole-home battery like Tesla Powerwall?
A whole-home battery (Powerwall, Enphase, Franklin Electric) is a fixed installation that ties into your home’s electrical panel and can back up your entire house or specific circuits. They cost $10,000–$20,000+ installed. Solar generators are portable, cost $400–$4,000, and power individual devices via outlets — but don’t integrate with your home’s wiring (without an optional transfer switch kit). For renters, apartments, or people who want flexible backup without installation, solar generators are the practical choice.
Do I need a transfer switch to use a solar generator during a power outage?
No — you plug devices directly into the solar generator’s outlets, just like a power strip. No transfer switch or electrician is required for standard use. Transfer switch kits (available for the DELTA Pro 3 and Jackery 2000 Plus) are optional add-ons that let you connect the generator to specific home circuits through your electrical panel, which is more convenient for running hardwired appliances like a refrigerator, sump pump, or furnace fan. They require a licensed electrician to install.
How many solar panels do I need to keep a home solar generator charged?
Match panel wattage to the generator’s max solar input. The DELTA Pro 3 accepts up to 1600W — you’d need 4–6 panels to approach that. The AC200L and Jackery 2000 Plus accept up to 900W (3–4 panels). The DELTA 3 Plus accepts up to 500W (2 panels). In practice, 2–4 hours of peak sun per day with 400–800W of panels will partially or fully replenish a 2kWh unit if you’re using moderate loads — keeping the fridge running and devices charged.
Is it safe to run a solar generator indoors?
Yes — all five units in this guide use LiFePO4 (LFP) batteries and produce no emissions. They are safe to use and store indoors. Keep them away from heat sources, in a dry environment, and within normal room temperature range. This is a major advantage over gas generators, which must never be used indoors due to carbon monoxide risk.
