I with Growatt would add an "SUB" function. First use solar, then utility and finally battery if the other two are insufficient to feed the loads.

Did you add the individual controller/inverter(s) as dataloggers? I finally have it working on my 2 Growatt inverters. It took me longer to get it working then the physical installation of the inverters. Setting up the ShinePhone app and dongles was the most un-intuitive process I've...

I have 2 Growatt 3000's wired as 240V split phase. 400 Amp Hours of 24V LifePO4 batteries. Float voltage set to 27.6V, Absorption voltage set to 28V. Maximum charge amps is set to 20A. Battery voltage is now down to 25.9 V and the charger still has not kicked in to maintain the float voltage...

I recently bought a pair of Growatt 24V SPF 3000TL-LVM AIO's and have them connected as 240V split phase. I bought Solar Assistant and have it up and running, but...I can't consistent see both inverters. On the SA configuration page the USB port setting shows 2 devices, one is "USB0" and the...

Has anyone ever heard of or have any experience with the above named panels. Here is the Amazon link...

My Growatt manual doesn't show an error(or fault) code 16. It does show a "warning code" 16 which is "parallel input phase error". If this is what you mean: Does the generator output split phase 220(240)? If so...is each Growatt hot input wired to a different phase?

I'm getting ready to hook up solar panels to my MPP Solar PIP 1012LV-MS AIO. The following specs are listed in the pdf I downloaded: Max. PV Array Open Circuit Voltage = 102Vdc PV Array MPPT Voltage Range = 15~80Vdc I'm a little confused about the MPPT Voltage Range... Does this mean that if...

Here is a video that is exactly on point:

I'm also in NJ and am curious how those panels from Randolph worked out for you

See post #38.

See this Youtube video: Same inverter...same complaint

Just spitballing here, but: Assuming that both the Pi and the router have a somewhat constant and predictable draw, couldn't you use the Pi to control a relay via a gpio pin. The relay would switch the DC-DC converter on/off based on a timer loop (or cron job) running on the Pi. This might...

No, I haven't. I'm still operating with 12V components (batteries & inverters). I brought it up because, I too am still in the "head scratching" phase of upgrading to higher voltage components. This device seems to address the issue of one BMS shutting down the output of both batteries (or input...

For you folks putting 2 12v batteries in series to get 24v (nominal) and having power shutting down to the inverter because 1 battery went low, have you considered using this item?: https://watts247.com/product/eq-24-2-24v-battery-balancer-balances-2-x-12v-batteries-in-series/

If you don't mind, can you tell me how much Signature charged you for shipping those 8 panels? I also live in NJ and have requested a shipping quote from SS twice and never got a $$$ estimate, just a response that my request was being forwarded to their shipping dept.

Yes, weight is certainly an issue and I'm sure the panels currently available are lighter then the older panels. The major concern for me was/is "sail area" of the panels. Years ago, when I was re-sheathing my roof I had several close calls with going airborne or letting the plywood go. The 100...

Take a look at: https://www.amazon.com/gp/product/B082LV7RKL/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I have both the 5A and the 20A Expert Power chargers. They both still work after 1 year of intermittent service. The 5A will be slow going to "fill" a 300AH battery from a low SOC, but...

Speaking as a senior citizen DIY'er (and I mean literally "DO IT YOURSELF") 100 Watt panels are still physically manageable. They allow me to still play the game. Also, there are quite a few 100 watt panels available on Amazon that ship "free" via UPS or FedEx ground for Prime members. The...

Here is the calculator I use. (caveat: I'm a simpleton): http://www.solarelectricityhandbook.com/solar-angle-calculator.html

I bought this one on Amazon for that very purpose : https://www.amazon.com/gp/product/B07P8M7N9F/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 (I'm NOT affilated with them in any way)

I too have been wrestling with this issue on my mpp-solar PIP LV1012MS inverter/charger. I have seen the suggestion to tie the neutrals of the AC Input and AC output together, but am hesitant to do that becaue of the possible unforeseen consequences. It seems like such a simple solution. You...

Hello all, A newbie here, looking for opinions on this Li-on battery pack for sale at BigBattery.com: https://bigbattery.com/product/24v-100ah-li-ion-battery-box/ All of my research and purchases have involved LifePO4 cells so I'm not sure if Li-on batteries for solar/backup purposes is the...

A good place for info on tricky earth grounding issues is https://forums.mikeholt.com/. It is not specific to solar but this guy is an expert on grounding. IIRC, a while back, his criticism of Generac's standby generator installation manual (re: grounding) caused Generac to correct their manual...

I'm a Costco member, but I can't find the batteries you mention on their website. I'm currently exploring my options for batteries. Any chance you can post a link to them? Thanks.
