Solaris | Helios | Complete Home Backup System

Q: What is the Helios home power backup system?
A: A home power backup system is a set of devices that provide backup power to your home in case of a power outage. It typically includes a battery, an inverter, solar panels, a charge controller, and some sort of automatic transfer switch.

Q: What are Delta Pro units?
A: Delta Pro units are solar-powered battery backup systems made by EcoFlow. They are designed to provide backup power for homes and businesses. They combine a lithium battery, an inverter, an MPPT charge controller, a DC charger, and many AC and DC input and output options.

Q: How many Delta Pro units are needed for a home power backup system?
A: The number of Delta Pro units needed depends on the power requirements of the home. In this case, the system uses two Delta Pro units, each with 800 watts of solar. It is expandable up to a battery capacity of 25kWh total, and up to 2400 watts of solar.

Q: What is the EcoFlow Smart Home Panel?
A: The EcoFlow Smart Home Panel is a control panel that connects to the Delta Pro units and allows you to monitor and control the power output of the system. It displays information about the system's status, including the battery level and the amount of power being generated by the solar panels. It can power up to ten circuits in your home, and there are options for split-phase, GFCI, and AFCI circuits to be wired in. It is installed next to your electrical panel.

Q: How does the home power backup system work?
A: The solar panels on the Delta Pro units generate electricity from the sun, which is stored in the Delta Pro batteries. When the power goes out, the inverter converts the DC power from the batteries into AC power that can be used to power appliances in the home. The Smart Home Panel allows you to monitor and control the system, and it can be programmed to prioritize certain appliances or charge devices when the system is generating excess power. It is an automatic transfer switch, and can be set to provide Uninterrupted Power with a lag of 20ms in the event of an outage.

Q: Are there other ways to charge my system besides the solar panels?
A: Yes, this system includes adapter cables that can charge the Delta Pro units from a house AC outlet, a regular vehicle 12V outlet, or an EV.

Q: How long can the home power backup system provide power?
A: The length of time the system can provide power depends on the power requirements of the home, the size of the batteries, and the amount of sunlight available to charge the system. In general, the system can provide power for several hours or even days, depending on the circumstances.

Q: Can the home power backup system be used off-grid?
A: Although the Delta Pro units can be used as standalone off-grid units, the Smart Home Panel is not designed for off-grid use. Please see our Complete Solar Solutions page for off-grid options.

Q: Can the home power backup system be installed by a homeowner?
A: Yes, the home power backup system can be installed by a homeowner, but it's recommended that you work with a qualified electrician to ensure that the system is installed safely and meets local building codes.

Q: What appliances can be powered by the home power backup system?
A: The appliances that can be powered by the home power backup system depend on the system's capacity and the power requirements of the appliances. In general, the system can power lights, computers, TVs, and small appliances, but it may not be able to power larger appliances like refrigerators or air conditioners for extended periods of time.

Q: How often do the batteries need to be replaced?
A: The batteries in the Delta Pro units have an extendable warranty of up to five years, and should last for at least 6,500 charge cycles before needing to be replaced. However, the lifespan of the batteries will depend on how often they are used and how well they are maintained.

Q: Is this system expandable?
A: Yes, each Delta Pro unit can support up to two DELTA Pro Smart Extra Batteries or Smart Generators, for a total of four. Additionally, you can add up to four more Rich 200W 24V panels to the system, simply by adding them in series to the four existing strings - no other cables or adapters are required. Note that you must add two at once, so that the number of panels in each string to each Delta Pro remains the same. You do not have to expand both PV arrays at the same time, however.

Q: What maintenance is required for the home power backup system?
A: The home power backup system requires minimal maintenance, but it's important to keep the solar panels clean and free of debris to ensure that they are generating maximum power. It's also important to check the batteries periodically to make sure they are holding a charge and to replace them if necessary.
