1. Introduction

With the increasing prevalence of photovoltaic (PV) systems on private roofs, many system owners are asking themselves: How can they use the solar power they generate as efficiently as possible? Especially in times of high electricity prices, it is worthwhile to make optimal use of self-produced electricity instead of simply feeding it into the public grid at low feed-in tariffs. In this article, we show you how you can use intelligent energy management and modern storage technology, such as the Zendure SolarFlow 2400 AC, increase your own consumption and reduce your energy costs in the long term.

2. Why use PV surplus?

A PV surplus occurs when your photovoltaic system generates more electricity than your household currently consumes. If not used, this surplus flows into the public grid, where it is paid for at just a few cents per kilowatt-hour. It's much more lucrative to use the surplus yourself. Every kilowatt-hour you use yourself saves you the cost of purchasing electricity from the public grid, thus increasing your independence from rising electricity prices.

3. Intelligent load shifting and power storage

In order to use as much solar power as possible, two measures are particularly effective:

• Load shifting: Consumers such as washing machines, dryers, water heaters or electric cars are automatically operated when a particularly large amount of solar power is generated.

• Power storage: Excess solar power is temporarily stored in a power storage unit and used later when needed.

This is where modern technologies such as smart plugs, load management systems and intelligent power storage come into play.

4. Example: Zendure SolarFlow 2400 AC as a flexible storage solution

A particularly flexible solution is the Zendure SolarFlow 2400 AC This innovative plug-and-play system is suitable for both smaller balcony power plants and larger PV roof systems.

The most important features of the Zendure SolarFlow 2400 AC at a glance:

• Flexible capacity: Start with 2,88 kWh, expandable up to 17,28 kWh

• High security: Long-lasting LiFePO₄ batteries

• High efficiency: Efficiency of 96,5%

• Intelligent control: AI-based ZENKI Home Energy Management analyzes consumption, weather, market prices and automatically optimizes energy flows

• Simple installation: Plug-and-play via Schuko plug without an electrician

• emergency power function for greater security of supply

• Convenient control via app

These properties make it... Zendure SolarFlow 2400 AC the ideal solution for households that want to achieve maximum self-consumption and at the same time reduce electricity costs in the long term.

5. How AI-supported energy management works

The one in Zendure SolarFlow 2400 AC iintegrated ZENKI Energy Manager continuously analyzes:

• the current consumption in the household,

• the weather forecasts,

• the current electricity market prices and

• the charge level of the storage.

Based on this data, the energy flow is automatically optimized. The response time is just 3 seconds, and the control operates with a precision of 1 watt. This minimizes unnecessary grid consumption and optimally covers even small standby consumption. According to Zendure, this can result in savings of up to 42% of electricity costs is possible.

6. Further measures to optimize PV use

In addition to the use of intelligent storage solutions such as the Zendure SolarFlow 2400 AC There are other useful measures:

• SmartPlugs: Smart sockets control traditional household appliances specifically, depending on the current solar power production.

• Central energy management systems: Automatically coordinate multiple consumers in the household.

• Local electricity marketing: Give excess electricity to tenants or neighbors (observe legal requirements).

• grid feed: Surpluses are fed into the public grid and remunerated.

By combining these measures, self-consumption can be further increased and the profitability of the PV system can be increased.

7. Fazit

Thanks to modern technology, the intelligent use of PV surplus is now easier and more profitable than ever. With smart energy management, flexible load shifting and innovative power storage systems such as the Zendure SolarFlow 2400 AC Households can maximize their self-consumption, reduce energy costs, and become more independent from the electricity market. The Zendure SolarFlow 2400 AC's easy installation, modular expandability, and AI-supported management make it an attractive solution for today's and tomorrow's energy supply.
