When mine came he pulled the meter then checked to make sure the house side of the meter was not energized (to confirm the system wasn't backfeeding while 'grid down'), then put the meter back in and that was it. He didn't care at all that I was using PV and batteries in zero-export mode.

I was scrolling down just to make this comment. I ran on limited to load/no sell mode for 5 months waiting for PG&E, and with the default I think 20w or 40w zero export limiter, I saw maybe a handful of little spikes to the grid. I would think setting to 200+ watts would make it even less...

I just got PTO a couple weeks ago, so most this data is with low throughput doing only self consumption. Now that I’m selling back maybe it will change some?

I just got PTO a couple weeks ago, before that I had the sol ark setup with ‘load first’, so it would start inverting power to load as soon as the sun came up, and only started charging after pv exceeded load. Since getting PTO I’ve set it back to ‘battery first’, and the battery gets 100%of the...

Yikes, I’ll have to look more into that. 30w/battery, so 90w for me, 24 hours a day, for 30 days, 64kW/month just for the batteries to run themselves?

I have Foretress eFlex batteries on a 15K, and notice that the charge/discharge efficiency seems to be pretty bad according to the data. I do have some cooling fans coming directly off the battery bus so that is part of the issue, but it can’t be using that much power. It looks like my...

It works fine using the CAN port, most the details are in the link below. This references Fortress batteries, but the Sol-Ark/Solar Assistant info is the same. So if you are not already using the CAN port you can use this, if you ARE using the CAN port for your batteries you just have to make...

Related for anyone wondering, because I just messed with this recently. I have lithium batteries, so there is no ‘need’ for the battery temp probe to be hooked up, but I wanted to use it anyway to monitor battery compartment temp vs BMS temp. Well I found out that when you are closed loop, and...

This is my thinking also. If you have net metering and no TOU, no reason to use the batteries at all unless the grid is down. Any ‘savings’ by discharging the battery are negated by having to use PV to recharge is the next day anyway, so your ‘net’ is the same. BUT you lost efficiency due to...

I think your TOU times need to be fixed, the manual says they need to be in time order, so from midnight (at the top) to midnight (at the bottom). It looks like you have a 7am setting at the very bottom? Other than that I think your settings should do what you are asking, is there something...

There have been a couple updates to the PVPro platform recently (you can see the release notes on the website), last one was 5/23. I was having a couple strange issues with my new install, and had to reseat the Wi-Fi dongle once to get correct data again. Opened a ticket with sol-ark, they said...

I'm on my first day running my house behind a 15K, and have a couple questions. First, prior to today, the SA was connected to solar, batteries, and grid (via a main panel that breaks out a grid connection to the SA, and one to my bypass transfer switch). So all the SA saw was the grid...

Is there any specific code I can reference here? I.e. can conductors at the end of a wire be cut/modified? Do all four poles of a quad ganged breaker need to be filled? Can wire gauge be used that is not specified by the breaker manufacturer? I would assume these are all no-nos, but would like...

Funny story. The electrician doing the panel upgrade had no idea what he was in for, the solar guys didn’t explain this setup to him before he arrived on the job. They didn’t have a very good plan either, so I could tell they were scrambling trying to get the work done and power turned back on...

Main panel was replaced as part of the project. They re-used the old breakers, including that very old one. The rest of the breakers aren’t that old, just this one.

If I setup my TOU settings for M-F and leave Sat/Sun unselected, what will the behavior be on those days? Does it just completely ignore TOU and not use any battery power, and just keep the batteries at 100%? Does anyone who has M-F TOU leave sat/sun unselected, or to you just leave it on all 7...

Thanks all. This hasn’t passed final yet, so I hope this was just temporary and they are planning on fixing it, but I will make sure they do.

This was my other concern, is this really still a 200A pass through, or only 100A since it’s only using ‘half’ of the breaker?

I’m in the middle of an install by a solar contractor, and have a question on how they have the main panel breaker wired. This is a SolArk install, so the SA is powering the entire panel via the main 200A breaker. They specified 3/0 copper cable, but the 4-lug main breaker doesn’t support that...

Just asked support and got this: "No, the MySolark app is not live yet. We will be notifying customers once the move is complete. We expect to transition later this month. "

Has anyone been able to use MySolArk yet? My system is being installed now, wondering which way to go.

With TOU disabled, once it hits Gen Start SOC, it will charge back up to 95%. With TOU enabled, it charges to either A) the set TOU SOC with charge enaled, B) stops charging completely if it hits the next time slot with Charge disabled (same as your test results), or C) 95% (I suppose).

Well I found a calculator, this helps understand what they are looking for. The eFlex battery datasheet shows two continuous discharge rates, 'recommended' and 'peak (for 60 min)'. Using the higher of the two I get a 13kW system. Using the lower one I get an 8.6 kW system. So again that could...

Agreed, another thing I find confusing. I'm installing a Sol-Ark 15K, with 11.84kW PV, so everything in my system is above '10 kW', and yes the 'discharge time' is something I'm not sure how they are calculating. That is from the 'SGIP Handbook', can be found here...

It seems to be pretty clear about the 10 kW, just doesn't sound right since it's so low. Trying to determine if I'm reading the capacity correctly, and it seems like it? So with 3 48v 100Ah/5kw batteries puts you over 10 kW..

Hopefully starting an install soon, and trying to get realistic expectations for CA SGIP. I'm planning 16.4kWh of battery, it looks like that would put me in the 'Large Scale >10kW' group rather than the 'Small Residential <10kW' group? And I don't qualify for any of the additional rebate groups...

@GregTR I'd like more details on these parts. Hopefully starting my install soon, and I've already loaded SA onto a Pi with a M.2 SATA disk as I was afraid of SD card failures. I'd still like to configure backup though, wondering how you accomplished this.

I went through and watched the Sol-Ark training webinars, available on demand via their support page. There were a few things explained in those that SHOULD be in their user manuals, but are missing. One thing you guys might get a kick out of, when they were discussing Load first vs Battery...

That sounds right, but do you have the CTs installed and have you tried it? I wonder if Limited to Home will help the behavior you are seeing with PV not supplying your full load. I think most installs I have researched are using Limited to Home, including those with 15Ks running the whole...

On this one, when your TOU setting says 'Batt 100%', that means 'charge the battery to 100% and leave it there', i.e. it will not discharge any battery. If you are wanting the use battery to supplement PV power, you would have to keep that number lower, like 80% or whatever, so it knows it can...

For this one, it seems like your TOU setting at 7-8am might be trying to charge batteries. Have you tried to configure a 'slow ramp', i.e. at 8am leave the TOU battery low, like 20% or whatever your minimum is. Then at 10am increase it to 40%, etc, until you have it up to 100% by 3pm or...

With that setup my understanding is that TOU would stop discharging batteries at 15%. That would prevent them from getting to your 10% gen start threshold. What happens if you change gen start to 20%? It should start the gen as the battery crosses 20% on its way down to 15%, and the gen start...

I'm just about to start a 15K install, interested in more details in these issues. I would think this would be the default. In your experience does the 'load first' option do anything? Isn't that what this TOU setting does? 'Use battery power until they reach 15%' Again it seems like...

I think that's what he's saying. Go into Batt Setup, Charge, and enable Gen Charge or Grid Charge (whichever input your Gen is on) and set the Start %. Then go to TOU, enable Charge, and set the Off %.
