senec home battery v3 hybrid

Background on SENEC – Company History

SENEC was formed in Germany in 2009 with a focus on battery energy storage. They furthered development in this field from 2011 for use in PV solar systems, wind power and commercial use. In 2013 they expanded within the industrial storage vertical. In 2014 they launched the “Economic Grid” project with a vision of high uptake within the residential solar industry. By 2015  4,500 households received over one million kilowatt hours of free electricity.

In 2017 SENEC started expanding internationally with a focus on the markets in Italy and Australia. In 2020, they launched the new SENEC Home V3 Hybrid in Australia.

In a decade of growth, SENEC has sold over 20,000 solar battery systems. They’ve been the recipient of several awards with EuPD Research bestowing upon them as the “Top PV Brand Power Storage”. The SENEC Home received the “Top Storage System in 2017” from EuPD.

According to Dun & Bradstreet, Senec posted a revenue of $64 million USD in 2019 and has 159 employees at their German headquarters.

Basics of SENEC Batteries


The SENEC Home V3 Hybrid is their flagship lithium-ion battery range with a usable capacity of 4.5kWh or 9kWh for their two variations of this model. It’s an all-in-one “Apocalypse backup” hybrid battery inverter that comes with a 10 year warranty that can be extended to 20 years.

According to their datasheet It has an operating temperature range of 5 to 40 degrees Celsius which makes it suitable for moderate heat conditions indoors. With an rating of IP30 makes it suitable for indoor use only.

As it’s a lithium-ion battery, it’ll last for a long number of cycles and safety in use. With a maximum battery efficiency of 98% and a depth of discharge of 90%, you’ll get a lot out of this energy storage system for your needs.

SENEC claims on their website that it’s compatible with all systems regardless of the manufacturer. The advantage of their battery is that it can be retrofitted to an existing solar PV system. Up to 4 battery modules can be connected in parallel which would provide a combined energy storage of 18kWh and 36kWH respectively for their two variations of this model. This would more than enough be suitable for residential customers as well as within the range of commercial solar applications.

SENEC Battery – Key Featuressenec hybrid v3 battery

There are a number of features of the SENEC battery worth mentioning:

Long Warranty Period

Most of the solar batteries we’ve reviewed come with a 10 year warranty period which is standard in the industry. However, the SENEC  Home V3 Hybrid allows for an extended warranty of up to 20 years for those customers who want an extra piece of mind for their investment.

Monitor With SENEC App

You have the ability to monitor your battery storage system with their own app on your mobile or via their web app. This is useful for seeing how much energy you pull from the grid and the battery. You can use the app to keep track of when it’s optimal to feed your battery from the grid in off-peak tariff periods.

Compatible With All Solar Systems

The SENEC Home V3 Hybrid is compatible with all solar system brands. This is especially useful if you’re retrofitting the hybrid battery to an existing solar PV system. Thus it saves you time and stress that’s associated with adding battery storage later down the line. This is particularly handy if you’re not sure about investing in a hybrid solar system at the start, but then later on find you require battery storage as a backup.
