  • Optimize balcony power plant – New modules and 220V battery storage for maximum efficiency

    A person stands on a rooftop with solar panels and a balcony power plant, pointing toward a graphic showing a Zendure SuperBase energy storage unit. A modern house and trees are visible in the background. www.commaik.de

    In this blog post, I describe how I optimized my balcony power plant to maximize self-consumption and reduce dependence on grid power. I have installed new modules, improved the alignment and will integrate a battery storage system that supports bidirectional AC charging. I go into detail about setting up the EasyPower app and integrating the new APSystem EZ1 inverter into my Home Assistant for monitoring, as well as the results achieved and future plans to further increase efficiency. The aim is to maximize the efficiency of my system and make optimum use of the solar power generated.

    Powerstation for the garden house: the animal house in the garden with its large aviary requires electricity for the lighting and diesel heating. In order to reduce the electricity costs in the long term, I have built a PV island system which stores the electricity from the photovoltaic modules in special solar batteries. These batteries are now to be replaced by a mobile LiFePo4 battery.

    With a balcony power plant it is possible to cover the basic consumption of electricity in the household. But how do you monitor power generation? How do I know if the system is actually profitable? Quite clearly: with a program for analyzing, evaluating and monitoring PV power generation.

  • 800W balcony power plant easy to install & optimize by yourself

    To cover the base load I have installed a small 300W balcony power plant for quite some time. I was able to gain some experience and optimize my own use of solar power. Now I am replacing my 300W balcony power plant with a new 800W balcony power plant. In addition to the new PV modules, I renew the substructure, the microinverter and, of course, the connection to the house grid. During my rebuild, a few questions came up, which I would like to answer with this entry and my video:   👉 What components does a balcony power plant consist of? 👉 How to fix a balcony power station?…

  • Set up 2. balcony power station and connect in series.

    Two large solar panels, part of a balcony power plant, are mounted on a wooden platform outside a modern house, angled to capture sunlight beneath a partly cloudy sky. www.commaik.de

    Despite my balcony power plant in the backyard and lower electricity consumption, electricity costs keep going up. According to the http://strom-report.de, KWh of electricity costs an average of 34.6 cents. New contracts currently cost as much as 41 cents. It is therefore necessary to think about cost-effective alternatives and to add another module to my existing Balkan power plant. But can I connect 2 different PV modules together at all? Do I need a new inverter for two modules or can I continue to use the two old micro inverters?
