No judging please. Totally new to this whole power station/ backup battery thing.
Am I wrong in assuming that for the AC200L, the 2,400 w is total available OUTPUT from the unit and the 2,048WH is a measurement for time-of-use? If so, then adding a B300 wouldn’t change the output but would add time-of use?
Example. With the aggregate 4,812wh for the two units, if constantly powering lighting that draws 350w, could I expect a running time of a little over 13 hours?
Hi,
No worries—it’s great that you’re exploring power stations!
You are correct in your understanding. The AC200L has a total output of 2,400W, which is the maximum power it can supply at any given time. The 2,048Wh rating is the total energy capacity, which indicates how long you can use that power.
When you add a B300, it won’t increase the output capacity but will indeed extend the usable time.
In your example, with a combined capacity of 4,812Wh across the AC200L and B300, if you are powering lighting that draws 350W, you can calculate the running time as follows:
Running Time=4,812Wh350W≈13.75 hours\text{Running Time} = \frac{4,812 \text{Wh}}{350 \text{W}} \approx 13.75 \text{ hours}Running Time=350W4,812Wh≈13.75 hours
So yes, you can expect a running time of a little over 13 hours under those conditions.
You’re correct in your calculations, but it’s important to consider a few additional factors. The theoretical running time of 13.75 hours is based on the total capacity, but in practice, you should account for:
Depth of Discharge: It’s generally advisable to use only 90-95% of the battery’s capacity to prolong its lifespan.
Self-Discharge and Losses: There may be some energy loss due to the unit’s self-consumption and inefficiencies during the discharge process.
Taking these factors into account, the actual running time may be somewhat less than the theoretical calculation.
If you have any more questions, feel free to ask!
Thank you. Can you set the unit to shut off power when there’s 10% left… just in case?
The soc function is designed for this.
