Introducing the SolarTown Helios Home Backup Solar Kit - a comprehensive and efficient solution for powering your off-grid lifestyle. This kit includes two EcoFlow Delta Pro units, the latest and most advanced portable power station from EcoFlow. You get eight 200 watt solar panels, totaling 1600 watts of renewable energy. The Delta Pro is a compact, yet powerful device that provides clean and reliable energy for your home, RV, or cabin. With a combined lithium battery capacity of a full 7200Wh and a maximum AC output of 3600W per unit, this power station can handle lighter energy needs for multiple days, making it ideal for simple off-grid living.

The 200 watt solar panels included in this kit are designed to work in harmony with the Delta Pro, using a 2x2 series-parallel array for each Pro unit. They are high-efficiency, rigid-frame panels that can convert sunlight into usable energy, which can then be stored in the Delta Pro. The panels are durable and weather-resistant, making them perfect for outdoor use. With a total capacity of 1600 watts, they can recharge the Delta Pro units in just one average day of sunlight, giving you unlimited power whenever you need it.

The EcoFlow Smart Home Panel integrates the EcoFlow DELTA Pro units with your home to achieve a flexible, expandable home battery solution to store energy for later use. Link up to 10 of your home circuits for uninterrupted power during blackouts, smart energy management, and more.

This Home Backup Kit is perfect for those who want to have an easy-to-install emergency power solution that can be hardwired to home circuits. It functions as an Automatic Transfer Switch and can be set to provide Uninterrupted Power with a 20ms lag.

Frequently Asked Questions

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
