The one question nobody asks before signing up for solar is probably the one that matters most.
Not the price. Not the brand. What's actually covered in the warranty.
Sig Energy and Huawei batteries are very similar pieces of kit. Huawei comes with 15 years as standard and Sig Energy with 10, and you can add another 5 on top if you want the extra cover. Inverters from both come with 10 years.
If something does go wrong, the warranty doesn't just cover the repair, it covers the cost of reinstalling it too.
Ask those questions before you ask anything else.
