Once you get onto the subject of energy freedom, the question seems to keep popping up: Is it actually possible to power your entire house on solar and batteries? The answer is an emphatic yes, providing of course that the right system is set up. At BatteryEVO, we have the solar for your home combined with the backup battery-powered solution that will provide long-term energy independence. You can Power Entire Home with Solar and Batteries.
The Truth About Whole-Home Solar Battery Systems
Solar energy can power your entire home with a satisfactory configuration of photovoltaic panels, combined inverter and solar battery system, and energy management tools for advanced use. The average home solar power system size of 5-10kW will run on an estimated 20-30kWh of daily load; thus, it is important to choose fairly large panels in the residential category of 250-400W and install adequate nighttime storage from solar batteries to cover consumption after sunset.
It is also very essential to perform load profiling and analyze usage patterns and expectation from the grid backup to size the solar panel installation for domestic purposes. This is where BatteryEVO shines.
Meet BatteryEVO's Powerhouse Systems
WALRUS G4 Plus
It is a low-cost solar design in a whole-house unit. G4 Plus has a 16.5 kW inverter, a 23 kWh battery capacity, and extensive support for battery and solar combo for energy independence, making it practical to live off the grid. It even supports kWh-sized batteries for homes, which is crucial for making the most efficient use of the homes for extended outages.
WALRUS G3
Backed by a 12-kW inverter and a 22-kWh battery-the G3 is created to support AC-coupled versus DC-coupled battery configurations and an island-mode solar energy system ideal for solar + battery resilience in case of grid failures - and can perform emergency back-up power for essential homes in addition to full-load demands.
48V KING KONG 2
It's designed for modular expansion, this compact but powerful unit supports reserve battery capacity for inverter start-up, solar battery wiring layout and diagrams, and completely integrated with hybrid or off-grid solar system for full independence use cases. This is also very useful for backup power in emergencies.
How Long Can These Batteries Last During an Outage?
All systems designed to backup a PVESS-supported system for multi-day outages. A typical 10-kWh battery storage system will run an emergency circuits critical load panel for 24 hours, while our systems are designed to go beyond that. Store energy with high-capacity solar batteries; with BatteryEVO, you have the edge.
Thanks to recharge solar batteries with peak sunlight, you can indefinitely increase your runtime. Even cloudy weather doesn't affect solar performance; high smart power management keeps performance up on cloudy days.
Off-Grid vs Grid-Tied: What’s Right for You?
Going totally off-grid? Our systems cater to battery inverter charger for household purposes with home energy management (HEMS) integrated systems and design solar systems for priority appliances. Prefer a hybrid set-up? Enjoy grid-connected solar with battery storage, smart export guarantee (SEG) explained, net metering and electricity export policies, and easy add backup generator to solar installation for peace of mind.
Affordability and Incentives
Do you think that it might be unaffordable? BatteryEVO offers very competitive prices for the installation cost per watt for solar systems, and also evaluate quite fairly prices for battery storage per kWh. So besides that, make use of federal and regional solar tax rebates and consult for custom solar system design to find the perfect setup,
Combine with energy-efficient appliances for solar-powered homes, advanced maintenance of photovoltaic systems, and long-term maintenance tips on solar panels, and you are practically coming up with a system that guarantees maximum ROI.
Final Takeaway: Yes, You Absolutely Can
Yes-you absolutely can power your entire home from just solar and batteries-and BatteryEVO makes it possible and affordable. Be it the WALRUS G3, WALRUS G4 Plus or the 48V KING KONG 2, your path to energy independence begins here.

FAQ
Can I power my house with batteries?
Yes, it is possible to completely power your whole house on solar and high-capacity lithium-ion batteries-well, especially with systems like the WALRUS G4 Plus and WALRUS G3. These are the ones allowing a full house backup with battery power both during the day and at night, as well as with full load support using the inverter and solar battery combination.
How many batteries do I need to run my whole house?
In solar planning, the number of batteries equates to the daily electricity consumption averaging for most U.S. homes at 20-30 kWh/day. The most suitable battery system for most homes is a single 23kWh, such as the WALRUS G4 Plus, marrying power with efficient-weather appliance systems and periodical solar recharge in peak sun hours. Larger or energy-intensive homes may either utilize an array of units or turn to modular systems like the 48V KING KONG 2.
How big a battery do I need to run a house?
For the most part, homes would require between 10-23 kWh battery storage units for either off-grid solar systems or grid-connected systems with battery storage. BatteryEVO custom fits battery size for homes in kWh based upon individual energy profiles.
How long will a battery power your house?
Battery life span is determined by use and weather. For example, a 10 kWh battery would give a full 24 hours of essential home back-up power, while larger batteries in the WALRUS series can provide multi-day autonomy, especially when paired with PVESS-supported back-up and solar panel recharging. Our systems are designed for resilient solar + battery performance, even during extended outages.
