Long term effect of frequent overloads

[innovative dad]

The home battery system is paired with solar (10kWh capacity), and I've noticed it keeps hitting overload when a few big appliances kick on at once, although it recovers, I dont know if this kind of frequent stress is doing long term harm to the system, there are no critical faults showing yet, but I don't want to wait until one does
What can I do in this situation

 

[so what's the scenario]

Even if it's not throwing faults, that kind of stress could wear it down faster over time so be careful. It might be worth adding a soft start or load manager to help smoothen out those spikes.

Sizing a home battery for total capacity without considering instantaneous load handling is like buying a bathtub based on gallons and ignoring how fast the faucet runs. People treat kilowatt-hours like they're king, but it's the continuous and peak power rating (kW) that really matters when appliances kick on.

You're not damaging the battery per se, but you're stressing the inverter and possibly shortening its lifespan especially if it's running near or past its surge limit regularly. Get a proper load analysis done, or add a load-shedding relay or secondary inverter before something critical does fail.

I think the system is just getting pushed when multiple high draw appliances run at the same time. A few things you can do is to try staggering appliance use so the battery isn't handling everything at once, check if your inverter has an overload or peak shaving setting, or consider a small load controller to limit simultaneous draw
