Hello,
I have tried to get my question answered on the phone but no-one seems to understand my question,so here goes with a lengthy explanation.I was using a 350VA ups for back up it only had had a 12v 8ah battery that could only last up to a half hour at roughly 45watts,I recently bought 3 eb3a’s to replace them since they were at least double the UPS’s VA rating.Now the problem seems to be that the Tripplite UPS’s pass through the house current unencumbered while my eb3a fully charged to 100% will shut down at 600 watts even when the inverter is not triggered.It seems like the software will not let more than 600 watts pass through the eb3a’s from the wall plate.Which is perplexing to me because shouldnt the relay just pass the full current of 15amps from the wall in ups mode? I realize that during a power outage the eb3a is limited to 600 watts max but why is it also 600 watts max passing the current from the wall outlet when there isn’t a power outage? I thought since these eb3a’s do not surge protect the relay would simply pass current am I wrong in this assumption?
Thank you.
EB3A is not suited as real UPS
just search this forum. many problems.
Constant charging discharging cycling, Overheating, dropouts, high energy consumption, rando “overload” and so on
Got it. thanks for the reply.I got a call this afternoon from bluetti customer service.I guess the software was meant to match the 600w cutoff of the inverter.It’s a shame that no-one builds a “clean pure sign wave” affordable UPS that is affordable like the eb3a.Especially with the obsession nowdays with power having to be clean AC.These 3a’s would fit the bill for capacity,cost and pretty clean AC. Someday maybe someone will build a clean actual UPS that fits an actual need and not a toy.
There are many “of grid” / “hybrid” solar inverters oute there that can do this.
but most of them are for fixed install and not mobile
also why do you need clean power?
