Apex 300 Surge Capacity

Product Discussion BLUETTI Apex & AC Series

Wanted to to leave information regarding the surge capacity of the Apex 300 that I was able (after several emails) to get from Bluetti (Request 403142),

Below are the surge limits for the Apex 300:

"The Apex 300 can handle the following surge loads:

4032W < load ≤ 4608W: Surge capacity for up to 2 minutes.

4608W < load ≤ 5760W: Surge capacity for up to 10 seconds.

Load > 5760W: Surge capacity for 0.5 seconds."

In addition, these are not only the limits for a single Apex 300 unit - these limits apply whether you have a single unit or 2 or 3 units plus a Hub A1. As my contact at Bluetti explained:

. . .“when multiple units are connected in parallel, only the power capacity and storage increase. The overload capacity does not change, nor does the duration for which it can sustain that overload.”

For example, I have a 240V motor that in my house that needed a battery backup. It requires a startup surge of 38A (9,120 watts) . Based on this information I cannot use a single or multiple Apex 300’s for this since the maximum surge load is still 7,680 watts (32A @240V).

Hopefully this info will be useful to others, since I could not find it anywhere else in Bluetti’s documentation.

Hi

If you have 3 Apex 300 units with the Hub and the normal wattage is 11,520 (48amp) and should handle it fine.
I have 3 units and they start my 2 ton air conditioner that has a start up 59.5 amps with not problems.
I put a soft starter on the AC to reduce the load but the 3 Apex units had not problems starting it without the soft start added.

I run my whole house off of the 3 units and have had no problems at all.
When I was testing all of the appliances to find the ones I needed to replace with more efficient ones I saw the power draw up to about 12,500 watts (only while testing) and I had no problems.
