Seems better than I expected. Thank you.
Can you also let me know when I can expect to be contacted by whoever is expected to be taking these actions?
And by what type of communication … eMail? … if yes, what country will the eMail messages be sent from, I will probably need to edit my firewall to allow the messages to be received. For now most email from countries other than Canada and USA inbound email is being blocked because of excessive SPAM and messages containing Malware.
Elite 200V2 is the answer! At least for me 
with a minor potential issue still remaining to test … not yet confident that the Transfer time is fast enough to prevent reboots of PCs if Grid Power suddenly goes down.
I recently received a new Elite 100V2 and an Elite 200V2 … have been using both now for about 3 days. The Elite 200V2 works just like I want it to for a Standby UPs and so does the Elite 100V2.
However the EL200V2 has an additional ‘Time Control UPS’ and a ‘Customized UPS’ mode that allow me to time shift Grid Power usage from a Peak rate time (10X the cost per KWh of lowest rate) which works very well … but only for 2 different TOU rates on a daily basis.
Here I have 3 different TOU rates from Monday to Friday and 2 different TOU rates on Weekends. I will ask Bluetti to expand the number TOU rate periods and allow for settings for each of 7 days within a week … I hope they will be able to do this. This is a great idea for any of us that have to deal with TOU rates … ours are set once per year depending upon historical loads by time periods for the previous year.
The Elite 100V2 has the same ‘Time Control UPS’ and ‘Customized UPS’ menu items … but unfortunately these both behave the same as a ‘Traditional UPS’ … with the result that they continue to use Grid Power during Peak TOU periods … while the Elite 200V2 actually does not draw Grid Power during TOU Peak periods .
Probably a bug, I will report it to Bluetti later @BLUETTI_CARE or maybe they will pick it up from this message.
Hi @BPR, Thank you for your suggestion; we think it is very meaningful.
Could you please let us know the general region you are in? We have submitted this to the R&D department, and they will discuss the feasibility of setting up 5 different TOU electricity prices for 7 days a week next.
re: TOU pricing in Canada … there is much more variety of pricing plans than most people would guess. I hope the following will help others that want to take advantage of the substantial cost savings that TOU pricing provides.
Here is the current TOU rate table that is in use for the area where my Home is located.
Key rates High = 28.4 cents per KWh (was 28.6 last year) Low (overnight) =2.8 cents per KWh
I use the Ultra Low rate, and time shift the Electricity Usage for Heating, WebServers, PCs, all with a total of about 2KW consistent draw, peaking to about 4.5KW but seldom dipping below 2KW … using about 10 KWh of LiFePo4 batteries and 5 Inverter/Chargers which never run at more than 40% of load capacity. I now have about 20 KWh of batteries and multiple unused Inverter/Chargers that I intend to employ to expand the time shifting for more of the relatively consistent loads that I can re-organize with the still unused battery capacity.
I am now also considering migrating more of the time shifting load onto multiple Bluetti devices which seem to be much less susceptible to the over temp issues that I have been getting with too many Amazon supplied components. This is why …
I have found that there are unexpected safety concerns with DIY Inverter/converter installations … the most recently discovered issue was caused by a switch purchased from Amazon … SKU = https://www.amazon.ca/Ampper-Battery-Disconnect-Isolator-Vehicles/dp/B07JJSTFMN … the Inverter/Charger spec indicates a charging current of 35A @ 24V … but was measured at 34 ~ 38.5 V depending upon the SOC of the 24V200AH battery … temperature monitoring about 20mm from the switch contacts showed a daily range of low temp = 21C & high temp of 34C initially after first installed … rising to a range of 21C ~ 52C in about 30 days if not touched … switching it off then back on again reset the range to 21C ~ 34C … but the time period to measure the temp increase was shorter. At no time did the current going through the supposed 100A switch exceed 25A (after reducing the charger output to 70%) while charging … but during the times when the power was off and the output load was high it is possible that it could go as high as 85A which I am now convinced is a fire hazard.
A few days ago we did have a power outage of about 3~4 hours … I powered down one of the Inverters and consolidated the WebServer load on a single Inverter … increasing its load from 425W to 650W (Inverter capacity is 2KW continuous / 6KW short Peak) … within the 3 hours the switch temp had risen to 105C … I have decided to replace it with a different type.
A few months ago the same Inverter experienced an overheating of the 100A ANL fuse block (a few inches below the switch described above while the charger was still running at 100% capacity) that melted the acrylic cover and singed the wood that it was mounted on. It seems that the significant range in temperature was causing some loosing of the connections and increasing the resistance of the battery lug to connecting bolt connections … my initial reaction to that incident was to limit the charging current to 70% (<25A) add on some continuous temperature monitoring, and operate the switch at lease once per month to reset the progressively increasing high end to the temperature range … the recent power outage convinced me that is not good enough. Although I did not measure the actual current flowing through the switch my speculation is that it did not exceed 30A … and still it overheated what is supposed to be a 100A switch, the connections were tight when I switched over the load, I checked to be sure … but when I took it out of service were much easier to loosen than I think they should have been.
I recently tried a new tactic for time shifting the power draw … I used a EB3A as a UPS for a single PC and Cellphone charger, with a timer switch to disconnect the EB3A during the Peak rate time period … the run time using only the EB3A is inadequate, but can be increased to more than 4 hours by adding a 24V battery plugged into the EB3A charging port.
Except for the unexpected UPS output drops (only applies to older models), this idea works … some fine tuning of the external battery capacity is all that it will take to make this approach succeed without the unwelcome risk that comes with using DIY approaches … even when I am certain that I have the Specs and design right … the unreliable performance of too many of the DIY components is just too risky.
Hi @BPR, Thank you for sharing this with us. The information you’ve provided is extremely valuable—it not only gives us a clearer understanding of the needs and feedback from real-world usage but also serves as an important reference for us to optimize our products and services moving forward.
We have already reached out to the app department again promptly, conveyed your needs to them in detail, and emphasized that they must attach great importance to this situation, conduct careful research, and push forward with relevant improvement work. Thank you for your concern!
