    Cheaper to burn oil than run electric heat pump -)

    I also question current electricity price used in calculations. I am in CT (EverSource) and electricity price went down from 30+ to around 26 cents per KWh last summer.

    Discussion: How to get status information from your Powerwalls

    My Gateway (23.36.3) disabled local access with this message: Switch to Tesla Pros for a better commissioning experience The current experience is no longer supported It is the same while connected through TEG* or local network. Is there a workaround or cloud access is the only option available?

    I am not sure. It is somewhat recently that Tesla app added an option to charge from the grid. Prior to that everyone was under the impression that US solar tax credit for PowerWalls requires disabling charging from the grid.

    most people have solar with PowerWalls but I do not believe that program requires it. it simply makes more economic sense to have solar charging PWs and use that power during evening peak consumption hours.

    Enphase has a white paper specifically for PowerWalls. I think all interaction between IQs and PWs should be controlled by profile, not firmware itself. Enphase has plenty of standard profiles with different curves and delays for frequency shifts. It is also possible to create custom profile but...

    Since your supply line 200A you can potentially backfeed 48KW from ( PWs + PV excess) but utility company will need to agree to it. I think maximum number of PWs connected to one gateway is 11 but this limit depends on supply line resistance. GW has functionally to limit backfeed to specified...

    Tesla Powerwalls for backup

    I would think that ClimateMaster heat pumps are modulating, similar to Mitsubishi air heat pumps.

Unfortunately Mitsubishi controller does not show compressor engagement level...

    July house consumption in Tesla app shows 2400KWh. It is a huge increase from previously observed 600-1400. Daily consumption graph for July 20th and 21st has -2KW base with 7.2KW spikes for around 40-50 minutes. I assume that it is single stage AC activated by thermostat. 7200W - 2000 W (base...

    @TradeDC , How many PWs do you have in your system? @Redhill_qik , I do not think electricity consumption increase level can be explained by having house light bulbs on more than before. The increase is too large for that.

    actually data does not lineup. Meter readings show 8 KWh for July 20th and around 35KWh July 30th and 31st. Tesla does not have dip on 20th and readings for 30/31 are much higher than low number, 39.

    The meter reading on the bill stayed at “high watermark” from prior meter, which is very confusing to customers.

    My utility bills went up after installing solar panels and home energy usage is doubled based on Tesla app

    I doubt that you get a lot of economic benefit from PWs, especially in winter, so no loss in changing PW reserve to 100%. It will simplify the system by eliminating one variable. I forgot all I-210 meter codes. I think importing meter reading is 04 and exporting is 10. There are 5 or 6 counters...

    My utility bills went up after installing solar panels and home energy usage is doubled based on Tesla app

    Numbers in picture make more sense since electricity consumption reading starts from zero around July 14th (presumably bidirectional meter installation date). Export number is suspect since 12 KWh for whole month in July is ridiculously small. What did you set PWs reserve level to? Lower reserve...

    My utility bills went up after installing solar panels and home energy usage is doubled based on Tesla app

    Sorry, silly question. Did electric company install bidirectional meter? Regular meters count electricity export as debit. Take a look at Tesla app while PV production is measurable and exceeds house consumption and compare number for export in app with what meter shows. Bidirectional meters...

    Pricing in the program is rather unusual. It does not use amount of electricity (kWh) but average rate of feed (kw) across all events. I am glad that all events this year are 2 hours, not 3. My recollection is that pricing per kw was the same last year.

    My preference is the same as yours but admittedly there is zero financial incentive to follow this model. It is just to lower rather abstract number of power purchase from the grid. My PV system is more than 10KW so I pay $0.006 system benefit charge for each purchased KWh but even with that...

    Best way to connect 17kW of solar PV to one Powerwall?

    I do not think we have supporting evidence that PW activates power curtailment when charging current exceeds known limits. It is known that when SOC reaches high 90s frequency does go up, based on stored configuration.

    Best way to connect 17kW of solar PV to one Powerwall?

    I do not think backfeeding extra 12KW is doable (120% rule for panel). In case of blackout GW disconnects from the grid and uses PV to charge battery. Combined PV power exceeds ability of PW to absorb it and it does not matter if it is connected to GW solar input or main breaker panel. This...
