Valuable Suggestions

Grid Stability

There is a power outage about once every three months, and it usually lasts more than
two hours. I want the battery to power essential devices like refrigerators, medical equipment, network routers, and water pumps during outages, ensuring
basic household electricity.

Peak Electricity Usage Periods

My peak electricity usage is typically between 4pm and 10am. Since I can't always ensure that appliances like the washing machine, dryer, and dishwasher run during off-peak hours, I hope the energy system can store energy during off-peak times and use it during high-demand periods to help reduce electricity costs. I also want to maximize my solar system's self-consumption to increase
efficiency and savings.

High Grid Extension Costs

The high costs of grid installation are forcing me to consider installing a storage system. After comparing multiple options,
the energy storage system is the most feasible and affordable solution.

Lower Upfront Costs of Battery Installation

The cost of a battery is controllable, and with the current rate of electricity price
increases, the cost of buying electricity from the grid over the next 10 years will far exceed my upfront investment in a battery.

Increase energy independence

Due to significant fluctuations in electricity prices, I want to reduce my reliance on the grid and lower the load on it, contributing to the stability of the grid.

Environmental Benefits

By using stored renewable energy, I can lower my carbon footprint and contribute to environmental sustainability.

How do I calculate the right battery size for my needs?

The following calculation method applies to all battery brands. You can comprehensively evaluate whether it is necessary to install a battery and determine the appropriate capacity based on the installation cost, the warranty parameters provided by the manufacturer, current electricity unit prices, and actual usage.
