AC180P consumption issue comparing to EB70

Product Discussion BLUETTI AC Series
1

Hello Support team. There is an issue with new AC180P. I know this is unsupported scenario, but as you might know in Ukraine your product is very popular and customers use batteries in abnormal modes as well.
So lot of people connect your batteries directly in power socket during blackouts. First of all they switch off main input grid switch (or use dual automatic switch power device), then switch off all high-load consumers with particular circuit breakers and then swith on battery AC button. That provides limited electricity to appartments and houses. Light, some gadgets, routers, fridges etc.

I have 2 batteries now EB70 and AC180P
When I connect directly battery to socket as described above I have minimal battery consumption, let’s say 35w. Yesterday I have connected the same way new AC180P and had +260w consumption comparing to previous. Switching off one by one all circuit breakers I found that switching off air condition breaker stops extra consumption. Note that all air conditions are in standby mode. If I switch ON a single air condition in fan mode - the consumption goes back to normal, I mean +40w to minimal consumption. If I turn it off, back to stand by mode, the consumption increased to +260w to minimal consumption again.
I have switched the battery from AC180P to EB70 again - and there is no such behavior. Can you please provide some explanation or maybe solution?
Thank you in advance.

Hi @levchenko.alexander , I understand your concern, but this isn’t actually an issue. The difference in displayed power between the EB70 and the AC180P is normal. The EB70 shows active power, while the AC180P displays apparent power. This doesn’t mean the AC180P will consume more power to run the same device, so there’s no need to worry.

However, since the AC180P is larger, it will have slightly higher self-consumption. Therefore, we recommend using the EB70 for smaller devices and the AC180P for larger ones.

Thank you for response. You mean that even if AC180P shows current consumption like 300w (when eb70 shows 40w) in fact does not drain battery faster?
Do i need to switch off circuit breaker for air conditions when they are in standby mode or it does not matter for battery consumption?
