The demand for home batteries is growing enormously. More and more families and businesses are choosing to store their self-generated solar energy instead of feeding it back into the grid. A plug & play battery is the quickest and easiest way to do this. But which model best suits your situation – and more importantly: how do you connect it?
At Plugin Solar Energy, we offer three popular plug & play solutions: the Marstek Venus E Version 3, the Growatt Noah 2000, and the Growatt NEXA 2000. In this article, we compare their main advantages and how to connect them to your solar panels.
Marstek Venus E Version 3 – universal and powerful
The Marstek Venus E Version 3 is one of the most versatile batteries on the market. Its big advantage is that you can connect this battery to almost any existing solar panel installation. Whether you work with string inverters, micro-inverters, or a hybrid system, the Marstek can be integrated seamlessly.
- Storage capacity: ± 5.1 kWh
- Power: up to 800 - 2500 W discharge and 2,500 W charge
- Installation: easy plug & play, ready in just a few minutes
- Compatibility: suitable for all types of solar panel installations
This battery is ideal for those who want a universal solution that is not dependent on a specific type of inverter. Thanks to its high capacity, the Marstek is particularly interesting for households with higher daily consumption.
Growatt Noah 2000 – flexible and expandable
The Growatt Noah 2000 is a compact, modular home battery that perfectly suits systems with micro-inverters. The battery is designed to work efficiently with this increasingly popular technology.
- Storage capacity: starts from 2 kWh, expandable up to 8 kWh
- Power: approx. 800 W discharge, 2,000 W charge
- Installation: plug & play with micro-inverters
- Flexibility: expandable by adding extra modules
The Noah 2000 is ideal for those who want to start small and expand later. If you already have a solar panel installation with micro-inverters, this is the most logical choice.
Growatt NEXA 2000 – all-in-one solution
The Growatt NEXA 2000 goes a step further. This system actually has an integrated micro-inverter. This means you can connect your solar panels directly to the NEXA, without needing a separate inverter.
- Storage capacity: 2 kWh per module, expandable up to 8 kWh
- Power: up to 2,000 W charge and discharge
- Installation: direct connection of solar panels to the battery
- Additional advantage: possibility of emergency power supply
The NEXA is an excellent choice for those looking for a compact and complete system. Because the micro-inverter is already built-in, you need fewer separate components, and installation is exceptionally simple.
Which battery do you choose?
- Choose the Marstek Venus E Version 3 if you want a universal battery that fits any existing solar panel installation, with a large storage capacity.
- Go for the Growatt Noah 2000 if you work with micro-inverters and want a modular system that grows with your energy needs.
- Consider the Growatt NEXA 2000 if you are looking for an all-in-one solution where you connect the solar panels directly and immediately benefit from maximum simplicity.
