Ok so I’m not sure many Americans might understand these questions or issue (Do ya'all have 2 phase power over there?) ...but I’ll give it a shot. Maybe there will also be some other Aussies out there…(as well)
I have two phase power.
When it comes to solar and battery installs, trust me not even many engineers (let alone installers) know much about it : 2 phase is basically a complete PITA....
This is entirely why I am rolling out my solar bit by bit... learning along the way...
Think of each single phase like trouser legs dropping down from a metered belt buckle! The meter sees what going on measuring the energy flow in/out right at the waist - the belt opening. My Solar array and powerwall are on one leg (phase). The other leg has no solar or battery.
Now when the sun shines down here- it really shines! Sun was up at 6.30am and she was already charging by 7am- (We just hit max Summer Solstice I think its' today...so she;s really pumpin'...) The power wall was like fully charged from 10% to 100% by 10am yesterday!
Now the problem is whilst the PW was sucking all my solar collected, loads on my other “phase” ( the non green trouser leg) were sucking power off the grid. Normally without the powerwall (when the sun was up) , this didn’t happen. The solar (effectively) powered that phase. At least that’s what was balanced at the meter.
So how do I rectify this?
Do I install a wireless Tesla Gateway monitor at my main board? (All the Tesla monitoring is on the sub board - ie only one of the trouser legs)
Can I drop the charge rate on the PW somehow so the darn thing doesn’t charge up so quick? - ie spread the solar power collection a bit. There doesn’t seem to be a setting in the app for this?
Should I just put up some more panels on the other phase?
Eventually I intend to put in a Powewall3 on the other phase (with more panels) - so that’s the long term “solution” to this issue however they are at least 18 months away here I’d reckon. 3 months to ship the 15,000km on a coal steamer... at least the 6 months wait at the docks to unload... and what with all the inevitable rules and regulations here an’ all …
And I don’t want to spend money on extra equipment and truck rolls etc that won’t be needed in the long run…
So are there any short term fixes I can tweak in the interim?
Thanks!
