    California Members: NEM3.0 impact on NEM1/2 customers and what to do?

    Yes, that is the ‘reduced credit’ I was referring to. Some reduction of the credit given for export could be sensible to incentivize addition of storage to new solar installs. The biggest issue is that any reduction in export credit also impact the ability of summertime excess generation to...

    California Members: NEM3.0 impact on NEM1/2 customers and what to do?

    Yeah, just saw that myself. It would be great if he forced them to revise their decision to lop 5 years off of the legacy grandfathering period, but I suspect his concern is likely to be more focused on new solar customers. For them, it’s the greatly increased timeframe to breakeven and the...

    Orison plug and play battery

    Yes, to do a split-phase 120V install you would need 2 separate AC-coupled batteries (one per leg). But as far as ‘mounting’, the whole value proposition is that these are plug and play, so they just need to be plugged in. If you’ve got existing outlets where you want them located, you can...

    Orison plug and play battery

    The two outlets can be located anywhere. You can connect one to an outlet on one phase in one part of the house and a second to o outlet on the second phase in any other part of the house. The ‘split-phase’ capability is enabled by the 240V grid signal (which synchronizes the output of the two...

    Orison plug and play battery

    No, it seems to be compatible with 120 and 240, so you can plug two into 20A outlets on both legs and it will offset 120V split-phase consumption (as well as absorb either 120V AC solar power being generated on both legs or single-phase 240V AC solar power. What you cannot do is use a single...

    Orison plug and play battery

    I just ran into this ‘plug and play’ battery being developed by Orison: https://orison.com/product/ I’ve seen some posts on the Forum about whether these batteries can be used to provide backup power or not, but that is not my focus (nor is the question of whether the Orison battery is...

    SOL-ARK/DEYE Competitor - UL-Certified Megarevo 5KW-8KW 120/240V 48V Hybrid Energy Storage Inverter

    Eagerly awaiting your review / impressions. CanI ask what the 8kW model cost you? And any first impressions of build quality?

    SOL-ARK/DEYE Competitor - UL-Certified Megarevo 5KW-8KW 120/240V 48V Hybrid Energy Storage Inverter

    EV chargers are typically located far from where you would want CT sensors located, so wired or wireless communication with a multi-CT sensor Energy Monitor seems to be the preferred approach. Also, the handshakes and protocols needed between charger and EV to settle on a new charging power are...

    Adding Schneider XW Pro

    I’ve just started looking into diving into this world and pricing and options of buying Pi’s. Seems as though nailing down the minimum / maximum memory requirements for an energy monitor / charging control application like this is an important requirement to understand. When either of us first...

    Adding Schneider XW Pro

    Got it. As long as I’m under NEM, I’ll be generating more energy than I need on high-production days to fully charge my battery, so no need to avoid export until I’m pushed to the Successor Tariff… Yes, now I understand - your goal is to maximize AC-coupled PV energy conversion to battery...

    Adding Schneider XW Pro

    Yeah, that’s a bit of a concern I have charging right at the minimum. But also the reason I want to complement the AC-coupled charging power with DC energy from my DC-coupled array. Are these parameters of the EVSE? Are you on NEM? Why are you so concerned to avoid export during off-peak hours?

    Adding Schneider XW Pro

    I read the OpenEVSE website and it sounds as though the charge level can be controlled directly through the use of CT sensors. So just wanted to clarify you are using a communication protocol to control from your Rasberry Pi ‘brain’ rather than using the native controls… So the XW allows...

    Adding Schneider XW Pro

    This is a really helpful and complete description - thanks for going to the effort. Your system is a reference for exactly the system I hope to build, so I’ll be bookmarking this post and following in your footsteps. Just to be certain I’ve understood correctly, it is the simple MQTT...

    Nice! What is MQTT?
