Let’s take a look at the pros, cons and differences between these to help you make more-informed decisions during your transition to solar.Ī home battery backup system provides homeowners with the security and flexibility of storing their own backup energy. Homeowners have many options when it comes to backup battery systems, but how can you know which is best? The Tesla Powerwall 2.0 and LG Chem RESU are the two major players. As a result, we have seen an increase in both home solar energy systems and solar battery installations. People want less reliance on grid-based electricity. The new gateway box has 3 connections to the new main panel, to sub-panel1 (the previous main panel), and to the outside box.Home battery backups are still a relatively new technology however, their popularity among homeowners has recently grown substantially. The generation panel now has a bottom connection to the inverters, side connection to the Powerwalls and the top set of wires go to the outside box. Everything in them is fully backed up for a grid outage. Either surpass the 10 kW combined capacity of our 2 powerwalls.) And the previous panels are now labeled sub-panel 1 and sub-panel 2. (It pulls 11 kW or 17 kW for our model 3 or model X, respectively. This panel has the circuits which are not backed up for a grid outage, which is only the EV charger. The new main panel is connected to the outside grid meter, the new gateway and the EV charger. Inside, a gateway was added (long box on left wall) and a new main panel was added (long box on right wall). Starting with the outside, the box on the left was replaced and now has 2 sets of wires coming into it. Thank you again! This has been very helpful and giving me hope for a reasonable solution. If anyone has a recommendation for one in Southern California please pass along their contact information. It's clear I need to find a qualified electrician who specializes in solar electrical systems. I have photos of all of this if it would help. There is a designated breaker for the Telsa inverter.

It does not have a manual switch to disconnect from the grid. Am I still missing something?Īlso, how is an ATS (Automatic Transfer Switch) installed? My breaker box only has breakers. You mentioned AC Output but there's not a separate AC input on the Tesla inverter. What I understand from your reply, I just need to connect these three wires to the AC INPUT of Battery Backup system (AC Coupled system). All wires going into the inverter are coming from the solar panels. The Tesla inverter only has three wires, red, black and green that leave the inverter. I did research some AC Coupled battery backup solutions which is what I believe you are telling me will work with the Tesla Solar system I have. So, I will need an ATS to disconnect from the grid if the grid goes down.

For my purposes, adding a battery backup is all about when the grid is down. I back-feed the grid now when it is up and I do get paid for it by SCE. I'm getting closer to understanding.Ĭorrect. Thanks Jason for the reply and added information. Instead you should call an electrician that specializes in solar and battery installs. They don't want any part of any system that isn't wholly theirs and installed by them. The mistake you made is you called a solar installer. All you need to do is make sure that happens. If your solar and battery produce enough power, the household electrical system will just stop pulling from the grid. Oh and you don't actually need to 'grid disconnect'.

One bonus to having it extra dumb though is you can also tie solar and a battery inline with a backup generator this way. Having the battery controller to control the solar array and vice versa is just an extra upgrade.

If the AC power stops feeing in, the controller switches and the battery starts feeding DC to AC - it doesn't care whether the outages is because of grid failure or the solar array no longer producing, and it doesn't need to. So you can hook any battery controller up and have it behave as if it's grid tied - it won't even know you have solar nor will it care. Though it will incur a little bit of conversion loss, every battery controller has the ability to convert AC to DC and back. Whether it comes from microinverters or a single inverter, the end result is the same. First, the end output of the solar panels is 240 volts AC, and it will be connected to the house supply via the main electrical panel.
