Does anyone have a good stress test procedure to ensure the quality of the equipment after buying?
When I was buying a tiny 1KW aio for a friend I was very glad I decided to do all the testing on the bench (including 800W heater as load) when the AC charger decided to self destruct.
We simply packed it back in it's box, sent it back and a new one arrived 2 days later (this one smoked the AC charger too, so we returned it for a refund and later bought a a newer model).
I'd much rather find out the device I've got is defective, or being held by bubblegum before I invest lots of time into installing it.
My stress test procedure looks like this:
Power with just the battery, discharge it at full rated continuous power using a resistive heater.
Plug AC and set charging amps to maximum (assuming the battery is fine with it). Observe if it blows up, etc.
If not, discharge again. This time give it a load that briefly takes the surge current spec.
Then try to charge with solar with maximum power.
That's it.
Now I wonder where do I find a load to test the 12kW surge capability of smh-ii-7k (single phase).
