If you’re building a DIY off grid home—like a Connex home, cabin, or small residential space—you’ve probably asked:
Can one solar battery power my fridge, lights, TV, and even an air conditioner?
Short answer: Yes—with the right setup. Our eBoost 16kWh Lithium Battery paired with the Solo 6.5kW lithium battery home inverter delivers reliable 120/240 VAC split-phase power, fast solar charging, and DIY-friendly installation. Pair it with solar panels and you can recharge during the day and move toward true energy independence.
Understanding Appliance Energy Use
When planning a DIY solar panel system off grid, it’s important to know how much power your appliances consume:
| Appliance | Typical Power Use | Daily Energy Consumption |
| Refrigerator | 80–150 W | 1–2 kWh/day |
| LED Lighting (10–15 bulbs) | 10–20 W each | ~0.5 kWh/day |
| TV (LCD/LED) | 100–200 W | 0.5–1 kWh/day |
| Small Air Conditioner (DIY off grid AC) | 500–1200 W | 5–7 kWh/day |
| Electric Heater | 1500 W+ | 10+ kWh/day |
Tip: Essentials like fridge, lights, and TV are easy for most home solar battery setups. High-demand loads like air conditioning or electric heating require either multiple batteries or a residential solar energy storage system with backup generator.
How Long Can One eBoost 16kWh Battery Last?
Using the eBoost 16kWh battery with Solo 6.5kW inverter as an example:
-
Fridge + lights + TV only → 3–4 days
-
With small DIY off grid air conditioner → 1–2 days
-
With electric heating → less than 1 day
This shows that solar battery storage works perfectly for essentials. For climate control, add a second eBoost battery or pair with a backup generator.
Can Solar Panels Keep It Charged?
Yes—pair your eBoost system with solar panels and the Solo 6.5kW inverter’s built-in 140A MPPT for efficient daytime charging:
-
4 × 400W panels (1.6 kW) → ~6–8 kWh/day (enough for fridge + lights + TV)
-
8 × 400W panels (3.2 kW) → ~12–16 kWh/day (enough for full DIY off grid electricity)
Panel output depends on sun hours, shading, and panel tilt, but this setup makes fully independent off-grid living achievable.
What About Cost?
Many compare home solar battery price to Tesla Powerwall. Our eBoost 16kWh + Solo 6.5kW inverter bundle offers comparable performance at a lower cost. A full system with panels and optional backup generator typically ranges $7,000–$12,000, depending on capacity. Over time, investing in a residential solar battery system reduces reliance on the grid and protects against outages.
