System Overview

This battery-only kit charges from the grid and backs up your home during outages; compatible solar can be added later.

Ideal Applications

  • Whole-home backup for a typical home with one HVAC system (up to 200A service)
  • Whole-home backup for larger homes with additional major loads
  • Whole-home backup for homes with multiple HVAC systems
  • Agricultural power: multiple pumps and motors

What’s Included

  • One EcoFlow OCEAN Pro 24 kW hybrid system
  • EcoFlow OCEAN Pro 10 kWh batteries (battery configurations), with mounting and battery cabling
  • Meter Backup Switch with IslandDER meter collar, Smart Electrical Panel 40 or Smart Electrical Panel 8 (per configuration)
About the Meter Backup Switch option
Meter Backup Switch configurations include the ConnectDER IslandDER meter socket adapter. The collar installs between your utility meter and meter socket, isolates the home from the grid during an outage, and works with the Meter Backup Switch to move the whole home to OCEAN Pro battery power automatically. Meter collars need utility approval, and IslandDER is approved in select utility territories. Check with your utility before ordering; if a meter collar isn’t allowed, choose a Smart Electrical Panel 8 or 40 configuration instead.

Installation note: Site-specific wire and conduit, breakers, service and interconnection equipment, and permitting materials may be required. Utility and AHJ requirements vary; final design must follow manufacturer instructions and applicable code.

What Can It Power?

Built around the EcoFlow OCEAN Pro, a hybrid home energy system with stackable 10 kWh batteries, this kit delivers 24 kW of continuous 120/240V split-phase output. Every size uses the same inverter configuration: larger options add solar and battery runtime, while the inverter output stays the same.

What you can run
Everyday essentials

0.5–1.5 kW

Refrigerator and freezer, LED lights, ceiling fans, phone and laptop charging, modem, router and TV. These small and cycling loads are the starting point for long outage coverage.

Kitchen, laundry & larger loads

1.5–5 kW each

Microwave, coffee maker, washer or dishwasher as needed. An electric water heater, dryer, oven or range can use a large share of the output, so stagger them instead of running them together.

Cooling, pumps & shop tools

Check starting current

A compatible mini-split, central HVAC, well pump or shop tool may run when its running demand and starting current fit within 24 kW continuous and 49.2 kW surge. Check the actual equipment; tonnage or horsepower alone doesn’t confirm it. A soft starter can help some compressors.

Illustrative operating mixes
Refrigerator/freezer, LED lights, internet, TV and fans0.5–1.5 kW
Essentials + microwave or coffee maker2–3.5 kW while it runs
Essentials + a smaller inverter mini-split1.5–3 kW
Essentials + a 4.5 kW electric water heater5–6 kW while heating
Essentials + 3-ton central A/C running4–6 kW plus a large starting surge
Whole home: HVAC, cooking and laundry at once8–15 kW
Plan around the limits
Add up the loads that run at the same time and allow for motor starts. For a 24 kW split-phase system, keep loads balanced across the two 120V legs: a heavily loaded leg can reach its limit before the total does. A larger battery adds runtime but doesn’t raise the inverter’s output. Examples are planning illustrations, not guaranteed appliance packages.

How Long Will It Run?

Battery size sets how much energy you have. These battery-only estimates use 80% of nominal storage delivered to loads (24 kWh from 30 kWh, 32 kWh from 40 kWh, 48 kWh from 60 kWh).

Runtime = usable battery energy ÷ average load, starting full, with no solar, grid or generator. Average load includes cycling: a 1 kW appliance running half the time averages about 0.5 kW. Actual results depend on settings, battery condition, temperature and system consumption.

At 12 kWh per day

At 24 kWh per day

Cooling, heating and electric water heating can change daily totals substantially.

Charging Without Included Solar

This kit doesn’t include solar panels. It charges from the grid or a generator, and compatible solar can be added later.

When Solar Isn’t Enough

Utility available
Solar powers the home first, charges the batteries and can export surplus where your utility allows. The grid supplies the rest.
Grid outage: solar + battery
The system supplies only the circuits connected to its backup output, from solar and stored energy. Plan for the 24 kW output limit, battery discharge limits and motor starts, and shed large loads to extend runtime. A properly configured compatible generator can carry extended low-sun periods (not included).

Why This System?

The EcoFlow OCEAN Pro Battery Backup Kit (No Solar) is built around the EcoFlow OCEAN Pro, a hybrid home energy system with stackable 10 kWh batteries. Match the configuration to your daily energy use, the loads that run together and your installation.

24 kW for a useful mix of loads

120/240V split-phase output runs common household circuits and compatible 240V equipment. Manage what runs together and check motor starts for HVAC, pumps or shop tools.

Up to 24 kW output

Full output at three or more batteries (about 10 kW per battery below that).

Eight MPPT inputs

Flexible layout for complex roofs and large arrays.

Whole-home backup interfaces

Meter Backup Switch with ConnectDER IslandDER meter collar, or EcoFlow Smart Electrical Panel 8 / 40.

About the Meter Backup Switch option
Meter Backup Switch configurations include the ConnectDER IslandDER meter socket adapter. The collar installs between your utility meter and meter socket, isolates the home from the grid during an outage, and works with the Meter Backup Switch to move the whole home to OCEAN Pro battery power automatically. Meter collars need utility approval, and IslandDER is approved in select utility territories. Check with your utility before ordering; if a meter collar isn’t allowed, choose a Smart Electrical Panel 8 or 40 configuration instead.

Frequently Asked Questions

Does this kit include batteries?
Yes: 30 kWh (3 × 10 kWh Wall/Floor-Mount), 40 kWh (4 × 10 kWh Wall/Floor-Mount) or 60 kWh (6 × 10 kWh Wall/Floor-Mount) of EcoFlow OCEAN Pro 10 kWh batteries, per the option you choose.
Will it power my home during an outage?
Yes, for the circuits connected to its backup output (or the whole home with a whole-home interface).
What output does it provide?
24 kW continuous at 120/240V split-phase.
Can I sell excess solar to the utility?
Yes, where your utility allows and your interconnection agreement permits.
Can I connect a generator?
Yes. Use an inverter-style generator (3–5% THD) with 2-wire auto-start for automatic control. Generator not included.
Are all breakers, wire and conduit included?
Not necessarily. Site-specific wire, conduit, breakers, service upgrades and interconnection hardware may be required.
Will this eliminate my electric bill?
No specific savings are guaranteed. Rate structure, fixed charges, export compensation, usage and production all affect the final bill.
Do I need permits or utility approval?
Most installations need permits and inspections, and grid-connected systems need utility interconnection approval. Requirements vary by location.
Can this be installed DIY?
That depends on your jurisdiction and utility. Electrical work must follow manufacturer instructions, adopted code and any licensing requirements.
How do I know which configuration is right for me?
Use our kit selector, or contact SanTan Solar to match the system to your loads, usage and runtime needs.
