Re: [RE-wrenches] Whole Home UPS, Generator Charging
Jason, We have had no demand for systems with no PV here in Hawaii but we are just a small outfit. As far as generators and Sol-Arks. We have always managed to get generators charging with Sol-Arks but it seems to be a challenge. I'll state the 2 obvious things which have tripped us up in the past which I am sure you have already tried. Battery Setup->Charge-> Amps (Our guys alway forget this is DC Amps) Always program the voltage setpoint in case closed-loop goes down In off-grid installs we always install on the grid-input with CTs. It seems to work better for us regardless of the size of the generator.

Re: [RE-wrenches] All-In-Ones / Sol-Ark fail
Aloha All, Thank you Jason. This is a huge and surprising issue. So much so that I dropped what I was doing and called Sol-Ark to confirm. Mind you this was level 1 support, but I was told this is what the Sol-Arks are supposed to do and it is a feature not a bug. Their take is if there is any fault on any one string, the Sol-Ark assumes the worst and shuts everything down. I wonder what solutions could be implemented on future installs to prevent this from happening?

Re: [RE-wrenches] sol ark battery
Discover Rack Mount (you have to buy the outdoor rated enclosure separately) - Software is great and firmware is easily updated, standard rack mount aesthetics (not great looking) when installed without enclosure. HomeGrid (outdoor rated included) - Software is half baked and firmware is a pain to update, looks nice. Besides software we have not had any issues as of yet with either of these batteries.

[RE-wrenches] UL3741
Hello Wrenches, We are researching UL3741 and NEC2020s Photovoltaic Hazard Control System. Whether it is safe or not is a discussion for another time. After digging around a bunch it does not seem to be really geared toward us residential (grid-tied and off-grid) and small commercial installers. But I wanted to connect with folks who know the landscape better than us before we disregard it for the foreseeable future. UL3741 listed racking systems and solar panels are not the limiting factor, as there are enough manufacturers listed that we use regularly and can get easily. It appears that Midnite's MNSSR-600S-SS may be a good path for us as it has been tested with the Sol-Ark15k but from what I can tell not to UL3741 standards. It seems the short list of compliant inverters with a compliant racking system using Midnite's MNSSR-600S-SS is what would hold us back. As we don't actively use any of the listed inverters. Has anyone heard from inverter manufacturers that are actively working with a racking company on getting UL3741 or if they EVEN want to pursue it (besides Tesla, Solis, SMA, GrowWatt)?Specifically battery based hybrid inverters or charge controllers. I can't seem to find any. Thank you for your input.

[RE-wrenches] 120/240V to 200V 3 phase (Japanese Electrical Scheme)
Aloha All, I have a project that requires powering 6 different pieces of equipment (mostly small motors) from East Japan that require 200V 3 phase (L-L-L) at 50Hz (though 60Hz appears to be OK), a unique electrical scheme for sure. The amp requirement for the various pieces of equipment ranges from 0.75A to 6A. For a total maximum load of 28 amps. The site is off-grid with standard 120/240V North American Electrical Scheme using a Sol-Ark 15kW. My initial plan was to use Digital Phase Converters from MYUNG YOUN ELECTRONICS for each device but after seeing the wiring in the control panel and power distribution box in person there is no room to do this. Plus the entire panel would need to be rewired. Ideally, I would have one device that converts the electricity appropriately (transformer, VFD, etc). I have reached out to several EEs and am awaiting responses. In the meantime I figured the hive mind of the Wrenches group may have some ideas or know somebody that would. As always, thanks for everyone's time.

Re: [RE-wrenches] Optics
I started poking through EnerSys's (The most recent owner of Outback) SEC filings in hopes to find who the new buyer is. I found nothing related to the sale but found this in their most recent quarterly report : On November 8, 2023, the Company's Board of Directors approved a plan to stop production and operations of residential renewable energy products, which include our OutBack and Mojave brands. Management determined that residential renewable energy products no longer fit with the company’s core strategy and resources will be better allocated toward commercial energy solutions for enterprise customers. The Company currently estimates that the total charges for these actions will amount to $23.5 million relating primarily to $22.6 million in non-cash charges primarily including inventory and an indefinite-lived intangible asset write-offs and $0.9 million in cash charges including employee severance and retention payments. The plan is expected to be completed in fiscal 2024. During the nine months of fiscal 2024, the Company recorded non-cash charges totaling $6.6 million primarily related to indefinite-lived intangible asset write-off and cash charges of $0.4 million related to severance costs. The Company also recorded a non-cash write off relating to inventories of $16.1 million, which was reported in cost of goods sold. To say I am curious about what is going on is an understatement.

Re: [RE-wrenches] REC modules - review?
We have installing REC for 15 years with no issues. George and his team have been nothing but awesome to work with. We have never had to file a warranty claims. As a certified installer the improved warranty and labor credit if there is a claim has been a great selling point for us as well. Their app for registering panels is easy.

Re: [RE-wrenches] Automatic load control
Aloha Howie, The Lumin Smart Panel has worked well for us. https://www.luminsmart.com/ Software is simple and tech support was on point. The app works well also. Bonus...you can remotely monitor power consumption on each controlled load. Two minor hang ups: 1. Having to run a separate "grid sense" circuit. This circuit has to be pulled from a location that is on the grid side of the Sol-Ark. This can be in a pain when the load you wanna dump is on sub panel clear across the property from the inverter. I am sure this the case with all these load shedding type devices. 2. You have to do a training to install them. It was a short webinar. Super easy.

[RE-wrenches] Looking for software platforms
Aloha All, We are exploring software platforms to manage service calls (HouseCall Pro, Service Titan, etc...) The feature set on these service call related platforms seem to be great for that component of our business but we also need to manage the full installation side of the business and every growing paperwork flow to make sure things don't slip through the cracks. Ideally these 2 needs would be met by one platform and allow us to move on from the Google Workspace kludge, which has been great up until now. I don't know if it is even possible! I am wondering if you all are currently using any software platforms to meet these needs (separately or together) and what your experience has been. Thanks!

Re: [RE-wrenches] HomeGrid batteries
That was a bit of a cavalier statement on my part. On paper the tech specs look good. The warranty (60% after ten years or 3650 cycles) and initial track record is what I think is mediocre. . I guess in comparison to Blue Planet most battery warranties look mediocre.

Re: [RE-wrenches] HomeGrid batteries
Aloha All, I am considering doing a job with one of these (14kWH) with a Sol-Ark 12kW for a client who is demanding them. Anyone have any recent experience with them? The price is good but all else is pretty mediocre.
