Our 7.38kW grid-tie solar kit helps you create a solar system that meets your energy needs, saves you money, and supports a greener future.
Annual Estimated PV Production:
18 x 410W (PV array wattage) x 1300 (average hours of sun) = 9,594kWh/year
Daily Estimated PV Production: 9,594kWh/year ÷ 365 days = 26.3kWh/day
Backup Power:
For systems requiring backup power, an AC-Coupled Grid-Tie Inverter and batteries are necessary. These systems are connected to the grid and can sell excess power back to the utility company.
To ensure your grid-tie solar system meets your energy needs and goals, follow these steps to configure your solar panels, inverter, and batteries for optimal performance and reliability. In this kit, we have already included the basic configuration of solar panels and an inverter, and you can choose the battery based on your backup power needs.
Grid-Tie Solar System Design Steps
Step
Action
Example
1. Assess Energy Consumption & Define Goals
Calculate daily energy usage by reviewing past bills and identify system goals, such as reducing electric bills 70% or providing backup power.
10000 kwh/yr * 70% / 365 days/yr = 19.17kwh/day
2. Calculate Solar Array Size
Determine the required solar array capacity using average daily energy usage and sunlight hours.
19.17kWh/day ÷ 4 hours/day = 4.8 kW
3. Determine Inverter Capacity
Select a Grid-Tie Inverter with a capacity slightly higher than the solar array size.
4.8 kW + 20% buffer = 5.75 kW
4. Plan for Battery Backup
Calculate battery capacity for backup power if needed and consider the system efficiency 80%
(19.17kWh/day × 1 day) /0.8=23.96kWh
5. Choose Your Battery Capacity
Consider your usage environment and choose between eFlex Max 5.4kWh and eForce 9.6kWh-19.2kWh outdoor battery and eVault 18.5kWh indoor battery.
Battery: eForce 19.2kWh for outdoor use
6. Determine the Number of Batteries Needed
Divide total watt-hours required by individual battery capacity.
23.96kWh ÷ 19.2kWh/battery ≈1.25
Round up to 1x eForce 19.2kWh battery

Frequently Asked Questions
Why is the power station not working after it hasn't been used for a long time?
Why is the power station not working after it hasn't been used for a long time?
If the power station is stored at a low capacity for a long time, lithium batteries will self-consume power, which may lead to a quick discharge. This leads to poor conductivity and a reduced battery lifespan, resulting in poor battery performance.
How should I store and maintain the power station?
How should I store and maintain the power station?
Standard shipping normally takes 3-5 days. Next day shipping is available on all domestic orders (for an additional charge). International shipping times depend on the products and destination (estimated at checkout).
