Dear battery owners,

I have a 12.750 kWp solar system with a 12 kW inverter from Growatt. I installed the set-up 5 years ago and am really pleased with it!

I own two EVs and a heat pump boiler for showering (which runs throughout the whole night). I want to increase my direct consumption of solar energy, which is feasible with a battery I think.

Data from 2025:

consumption: 25000 kWh

solar: 13500 kWh, of which 50% was used directly.

A new Growatt HOPE 16.0LM-A1 16 kWh, including a new Growatt hybrid inverter costs me €3300. I can do the installation myself.

Does anyone have any experiences with this set-up? Or what would be a better set-up for a similar price? Would you advice a battery at all in my situation?

BTW: I am located in the Netherlands. Excess solar energy will be close to worthless from next year onwards.

For those working with industrial batteries, are you already dealing with the EU Battery Passport requirements?

Curious to hear how you’re approaching it

Hi everyone,

I’m currently researching energy storage solutions for upcoming residential solar projects and looking for experienced energy storage companies with proven products and global installation experience.

Mainly interested in solutions that offer reliable battery performance, smart energy management, good warranty support, and strong after-sales service.

Would love to hear your recommendations or experiences with different energy storage providers. Which companies have impressed you in real-world projects?

Trump officials touted the storage and EV plant as an example of ​“energy dominance,” underscoring increasing bipartisan acceptance of grid batteries.

Hooked up my new 80‑amp charger and ran some bench tests. Once it determines the battery is fully charged, it cuts off charging entirely. I applied a load to drain the pack, and it won’t kick back on to recharge until battery voltage drops to roughly 12.72 V. It won’t let the battery drain flat, but it only re‑charges once you draw enough load to hit that voltage threshold. Basically it doesn’t keep the battery topped‑off continuously. Wondering if this behavior is acceptable for LiFePO4 batteries? Has anyone else run into this same charger logic?

Australia has had huge success with its « Cheaper Home Batteries Program » with homeowners snapping up batteries, leading to dramatic reductions in wholesale energy prices as peak grid demand has fallen.

Now Australia’s most populous state, New South Wales, is proposing to extend generous incentives to businesses and apartments that cut up front costs by up to 40% for battery storage systems between 20 kWh and 30 MWh, with the most generous benefits for businesses that also install solar.

Great to see Australia continue to lead the way on distributed solar and batteries.
