Achieving Energy Independence is a common dream of those who decide to Install Photovoltaics, but can it become a Reality? To date, it is not possible to become 100% independent from the Electricity grid but a good level of independence can be achieved thanks to Photovoltaic Systems with Storage.
Storage system conserves Energy produced and not consumed during the day by Photovoltaic Panels and makes it available in the evening/night hours. Thanks to the falling price of Batteries and Tax Deductions for Photovoltaics, there is a strong interest in Storage Systems. In this article, we will talk about 3 Best Drum Models on the Market in 2024.

How to Choose the Best Photovoltaic Battery
The choice of the Most Suitable Battery model for Photovoltaics is made in the design phase. Storage systems combined with Photovoltaic must be designed to achieve 3 objectives:
- More Energy Autonomy from Electricity Grid
- More self-consumption to maximize the use of electricity generated free of charge by Photovoltaics
- Fewer Costs on Bill

But How to Choose the Power of Battery to Install? Only a project based on the real energy needs of the family can indicate the correct sizing of the Battery.
Number of household appliances and electrical devices, as well as energy use habits in the home, are fundamental indicators for the sizing of a Photovoltaic System. No less important are Technical characteristics of the chosen model, such as:
- Efficiency
- Battery Type, such as Lithium-ion
- Warranty
Batteries for Existing Photovoltaic
Storage Batteries can be added to an existing Photovoltaic System also under Energy Account, with the exception of those who benefit from 1st Energy Account. The GSE regulates the installation of batteries on incentivized plants. In order not to Lose Incentives, Storage System must have one of these configurations:
One-Way Production Side:
This is configuration without drawing energy from production network. A rare configuration where storage systems are defined as “DC side” and can be of the “All in One” type (Integrated Battery and Inverter) or separate.
Bidirectional Production Side:
In this configuration, there is energy taken from the grid and the batteries are installed upstream of meter. Connection can be AC ​​side (the battery has an independent inverter) or DC side (Battery and Photovoltaic System are managed by Single Inverter).
Bidirectional Post-Production:
It is the most common configuration for Energy Account systems because it is connected to AC side. It thus maintains a distinction between incentivized photovoltaic systems and storage batteries.
Addition of Storage tank to existing system must be communicated to the GSE within 60 days from the completion date of works.
3 Best Models of Storage Batteries 2024
LG CHEM RESU
LG has built an excellent reputation in recent years as manufacturer of Storage Batteries, so much so that it has become a flagship in sector. The LG Chem Resu Lithium-ion Battery is our top choice for Residential Solar. With compact dimensions, it has highest energy density among Photovoltaic Batteries and maintains 80% capacity after 10 years of use.
LG conducts rigorous testing on its products, and storage systems are no exception. In particular, LG Chem Resu Batteries are subjected to safety checks against explosions and fires. Available in 3 different sizes for 48V version and 2 sizes for the 400V version. LG storage Batteries are guaranteed for 10 years.
Pylontech
Pylontech Lithium Iron Phosphate Battery is Scalable Storage system for residential Photovoltaic Systems. It is in fact modular system that allows the storage capacity to be increased over time. If, for example, after number of years energy consumption increases, simply add a module to have more power.
Lithium Iron Phosphate technology guarantees over 6000 cycles of use, more than 10 years, at 80% capacity. The elegant and compact design makes it suitable for any domestic environment. Costs for assembling Pylontech Battery are reduced, as it is very easy and quick to install. It is another battery that we highly recommend, we have installed it on several systems and it has never caused any type of problem.
MyReserve
Market for modular and attractively designed Batteries is growing. Besides Pylontech, another excellent Battery is MyReserve, born from the collaboration between SolarWatt and Bayerische Motoren Werke (BMW). Light and elegant, it can be combined with any type of inverter. In particular, it showed us great performance when we installed it with the Fronius inverter.
One of most interesting aspects of the MyReserve Storage Battery is the proprietary software. An algorithm manages charging and discharging of Battery according to the weather conditions and usage habits of the previous 3 days. In this way, it will always give the home right amount of Energy Required, without waste. SolarWatt MyReserve Battery has a 10-year full-product warranty and 5-year All-Risk warranty.
