Battery Discharge - Minimal Load?

B300K Battery connected to an AC300 Power Station.
What % daily discharge should one expect with the absolute minimal load (only native Bluetooth and Wifi)?

The ac300 is slightly less efficient just multiply the numbers by 24 for daily usage.

Thanks Kit,

Very useful.

So, even without load (AC&DC off), would it be normal to see a discharge of approximately 15% per 24 hours on an AC300+B300K combo? i.e. less than 1 week (without load) before needing recharging? ~2.4kW per week to get remote access???

Tad less efficient than my expectations.

Hi @ZUMinUK, Thank you for your inquiry about the AC300’s power usage. Here’s a detailed breakdown of standby consumption and our recommendations:
Power Consumption Analysis:
AC300 (outputs off): 19.6W/hour
Each connected B300K (standby): 2W/hour
Example (1 B300K):
Total daily drain: (19.6W + 2W) × 24h = 518.4Wh/day
This represents about 18% of the battery’s 2,764.8Wh capacity

To get the most out of your setup, we recommend turn off the unit when you don’t use it.

One great way to handle this is by adding solar panels if you can - with a steady solar input, those small standby power draws become practically negligible.

Special thanks to @Ktt for contributing to this discussion—community insights like this are invaluable!

Thanks Bluetti.

Makes sense, and shutting everything off has helped considerably.

WHICH SOLAR PANELS
I’m looking at connecting a pair (2) of these panels in series to DC1
ET Solar Elite 440Watt Solar Panel Bifacial Monocrystalline Full Black Panels (SKU: ET-NR748TBH440GB)

Elite 440Watt Solar Panel Bifacial Monocrystalline 26% Efficiency - Fu – VoltaconSolar

Would leave DC2 unused, with potential for connecting future panels; likely a small portable panel of flexibility when travelling/camping (PS: have tried a PV200D, but was only getting 30W)

Will this work?

Thx
