    I have been taking all the on demand classes available at no cost. Also they recently updated the training to include their latest products; IQ8 pv inverter, IQ battery 3T and 10T, combiner 4, and IQ Controller 2. The new battery is the same energy and power but a different form factor. @7.4” it...

    Update 9/24/2001 We are a year and a half into the 2kw pv install. We initially installed a system that met roughly half of our consumption needs. First year we: Produced 3400kWh Consumed 6600kWh (consumption metering is awesome) Consumption metering allowed us to see that our ac system...

    Thanks for your thoughts. This was mainly a thought experiment for me. Am currently getting set to submit a system design to Enphase for approval. Its an interesting process. Cheers, WL

    Thanks for the discussion. The inverter from the grid inverter would be the master inverter. It wouldn’t necessarily need a lot of kWh. Ensemble can be set to self consumption or whatever use case optimizes the system . When the grid inverter stops working the ensemble battery would provide the...

    Yo Svetz, was thinking about the best way to add a 3rd party battery/inverter to Ensemble to power a completely off-grid setup. Hypothesized that a big battery and split phase inverter would be best added on the incoming grid side of the enpower smart switch. What are your thoughts? Grid...

    AC coupled battery supplying essential sub panel with Grid tied Micro inverter - Wiring question

    If you want to DIY an Enphase Ensemble and Encharge system you will need to put yourself through the Enphase university program. It’s free and some parts are dense others short and simple. After the training you will need to follow a design review template. Full certification would involve...

    You can now purchase Encharge/ensemble equipment directly from the Enphase store and the prices are significantly cheaper than they were. Encharge 10 is $6720 and enpower smart switch is $1200!

    I saw that note too about IQ8PV requiring enpower and an envoy. Makes sense. For IQ8PV to function correctly it needs load control to protect larger loads.

    This is a blog post by Enphase detailing Power Start. A feature enabling the starting of high inrush current loads. Scroll down to view a chart detailing how many batteries are typically required to power certain loads and the accompanying soft starter that will help decrease initial start up load.

    Thanks again for your insights. Apologies if you already covered this... In off-grid mode: How well does enpower transition between solar and battery? What is the max load you have seen run by your solar-only in relation to its nameplate (AC) capacity? I’m aware that environmental...

    So the solar is curtailed when batteries are full, there is less load than solar is producing, and you are off-grid. Do I have that right? If you’re on-grid the power would be sent back to the grid with no need to curtail. So ideally it’s like an EV. You don’t want to leave home with a full...

    Thanks for all the updates. Haven’t gotten 100% caught up with the thread but excited to hear about all your experiences. You must have been on the waiting list with deposit/pre-order months ago. Surprised the installer allowed the AC to be on the backup circuit! U must have signed a waiver...
