  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    Sorry, I meant Grid-Tie. I edited the original post to reflect that. (y) I'm looking for a tier-one AIO unit that when a power outage occurs will automatically adjust production (on a sunny day) to my current consumption instead of loop cycling between using/charging the battery. I was told...
  • Post in thread: Inverter load (life/warranty) with electric dryer & stove.

    What made me hesitant was his assertion that no matter the capacity of the inverter, no system (although possible) should have a dryer or electric stove connected. He went even further by stating that even with 3 @ XW this was not recommended and would void a warranty claim to Schneider. I do...
  • Post in thread: Inverter load (life/warranty) with electric dryer & stove.

    Excellent point! Just found online the rating for my stove. Apparently it's 7,900W overall (240v). The bake element (oven) is rated for 2,400W; so 7,900W - 2,400W = 5,500W / 4 burners = 1,375W each burner. There are 2 dual (small/big) and 2 small. So they probably are between 1,500W for the...

    Great idea on the clamp DC ammeter. (y) Paid labor 75% of budget, Is that right/common? I was expecting less than $5,000 (13%) as I'll be providing all the parts. I know people that have installed PV + Batt systems (under a company contract) in 1-2 days (working from 7am-3pm) w/ installing...
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    For the past few months, I have been reading and learning about the differences in solar systems for “Grid-Tie”, “Strings” vs “Micro”, etc. I currently use 550k/month but we are planning to acquire hybrid/plug-in cars in the next 10-18 months. I have decided to start with a 6K system that is...
  • Post in thread: Inverter load (life/warranty) with electric dryer & stove.

    To summarize, it does not matter if the appliance it's stove. dryer, oven or heat gun; as long as I keep the sum() of all loads under the inverter/PV system rate capacity. Right? I know motors are another story. But right now my only motor is a 120v small Pool Sand Filter that uses around 408W...
  • Post in thread: Inverter load (life/warranty) with electric dryer & stove.

    Right now my plan is a grid-tied 1 @ XW with 1-2 MPPT 100/600 and around 7,000-8,000W PV (16 @ Aptos 440 bi-facial) with a 20-30kWh battery (haven't decided on brand yet in order: SOK, Kilovault, Fortress, Simpliphi or HomeGrid). Final batt pricing will dictate if a 20kWh or 30kWh bank...
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    Thanks for the info!!!! Basically the same here: Sun(+), hurricanes(-) & power company (-). I do plan to sell back but unfortunately our power utility company is the worst. We usually have multiple outages day/week. There have been times with outages for 3-4 consecutive days. So I'm looking...
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    I'm planing a system very similar to yours but only one XW (6k) first planing to add a second later; and . I was under the impression that the switching between PV/Batt/Grid was seamless in milliseconds. I'll try to contact the local Schneider installer to verify into this. This is from the XW...
  • Post in thread: Help understanding panel sizing capacity for Conext MPPT 100-600

    Thank you very much for the provided info. I read the PDF and was very helpful. I really don't want to stress the equipment. But at the same time, if the equipment is advertised as capable of 7-8kWh of PV input, then I suppose it should be safe. I do prefer to over-panel to get the all the...
  • Post in thread: Help understanding panel sizing capacity for Conext MPPT 100-600

    @pvdude and @FilterGuy. At the moment I'll be doing just 1 @ MPPT 100 600 with a PV of 2s1p generating a total of 427.12V @ 24.34A for maximum 7,680kWh - 8,400kWh (w/ bi gain). Eventually I'll be expanding to 12k. In that regard: Can I put a different size array in the second MPPT 100 600 for...
  • Post in thread: Help understanding panel sizing capacity for Conext MPPT 100-600

    Thank you very much for your input. For my planed Grid-Tied 6K system consisting of: 16 PV - Q-Cell (XL-G10-480BF) / 24V 480W (525W with bi) / Voc 53.39V @ Isc 12.17 Config: 8S1P generating a total of 427.12V @ 24.34A for maximum 7,680kWh - 8,400kWh (w/ bi gain). 1 @ XW 6848 PRO 1 @ MPPT...
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    I'm located in PR and from I was told apparently there's is "no limit" here. There's only one company and every month they compute your usage minus PV production. If you produce more than you use they just charge you a flat account fee (~$4) and rollover the excess production for next month...
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    Thanks! I will not be attaching a generator either (mine is 120v Honda EU 3000is) so it's not possible. But I do have very frequents grid-down failures of the Power Utility. I'll find unacceptable a PV system/inverter with battery backup having a 1 sec Grid > PV > Batt transfer time. That will...
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    Thanks for the thread references. Will check them both. I'm still in the planing phase deciding the best route/equipment to use. I'm more inclined on not to use AC micro inverters because of the battery compatibility issues and price vs kWh. I don't have any shadows in my roof, but will...
  • Post in thread: Help understanding panel sizing capacity for Conext MPPT 100-600

    So technically the max panels I could have on one MPPT 100-600 will be: String 1 (series): 11 PV @ 53.39V = 587.29V @ 11.12A 8 x "String 1" (parallel) = 88 @ Q CELLS 480 PV's = 587.29V @ 88.96A Is that correct? Although I know it will be around 42.2kWh exceeding the 6848kWh limit of the...
  • Post in thread: Inverter load (life/warranty) with electric dryer & stove.

    Thanks! I'll probably consider starting the system with the 2 XW from the beginning and be done with it; if install price is right. On a $35k+ the price for a 2nd XW is not so much more.
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    So this means connecting some PV with Micro-inverters to the AC2 of the XW? I'm planing 16 PV into the MPPT 100 600 for a total of 427.12V @ 24.34A for maximum 7,680kWh - 8,400kWh (w/ bi gain). But I could easily plan for 2 PV into the AC for 960W - 1,050W (w/ bi gain); and leave 14 PV on the...
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    Interesting! Thanks for sharing. I'm still in the planing phase for my batteries and haven't decided yet.
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    :ROFLMAO: I know what you mean. I've reading the XW/MPPT docs and there are SO MANY config parameters. I'm still expecting the install labor quote from a local Schneider certified installer. I'll consult and report back. If it's firmware upgradable all bets are off. This also happens with...
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    @400bird Thank you very much! Your pointers have help me a lot narrowing down my options and having a better understanding of the inverter function/features on the PV system. Actually since the Pandemic I've been working from home and doing less than 1,500 miles a year. Before that my daily...
  • Post in thread: Inverter load (life/warranty) with electric dryer & stove.

    Thanks! I do think the same way. Measure twice and cut once. I've been reading, learning and planing for months. The problem is finding someone to validate and install what I want without trying to push their own preferred equipment; and have the experience and professional requirements for a...
  • Post in thread: Advice for a new system 600kWh/month system $20-30k budget.

    Hi all! Newbie here, but I've been reading and researching for several months. I just bought a new house (2 phase 120/240v) and I want to install on-grid system (net metering) and storage that gives me a minimum of 24 hours backup. Where I live there are power outages several times a week for...
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    Interesting! I will look into the FLA forklift batteries setups. The $6k for 40 kWh and 20 years look awesome. What's the catch? I'm looking for no less than 20kWh and a target of 30kWh. 40kWh will be fantastic. So far I'm looking into SOK Server Rack 5.12kWh & KiloVault HAB V4 4.5kWh. But that...
  • Post in thread: Advice for a new system 600kWh/month system $20-30k budget.

    Thanks for the fast response! I live in Puerto Rico, but I'm planning to buy in Continental US (Online) and consolidate in Jacksonville for a cheap Freight Shipping cost to PR. I haven't check prices locally yet, but usually they 30-40% higher than continental or they are cheap china systems (no...
  • Post in thread: Help understanding panel sizing capacity for Conext MPPT 100-600

    Thank for the link. I'm not sure, but I think the issue brought by the installer is exactly about over paneling. As I understood it is that I should not have a production greater than 6,000W max on that MPPT 100-600 as it will significantly reduce the life of the controller. He pointed out...
  • Post in thread: Help understanding panel sizing capacity for Conext MPPT 100-600

    Thanks for the pointer POD. You are correct! I was assuming 150V @ 60A based on some specs I found online. With the correct specs, I still could do 16 PV instead of 14 PV for: 4 series of 2 PV of 53.39V = 106.78V @ 11.12A = 960W connected in parallel which will bring the total array to 8 PV =...
  • Post in thread: Help understanding panel sizing capacity for Conext MPPT 100-600

    @pvdude and @FilterGuy. Thanks for the previous pointers and detailed explanations. I'm getting a better grasping of of this PV world everyday. Hope someday I could help others the same way I received help here. Thanks!!!! Now I'm going for the semi-final step. Deciding the battery...
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    Thanks! I now want that too....
  • Post in thread: Questions setting up a new Grid-tie system (failures/redundancy/compatibility).

    Thanks! That makes sense. I was worried of a having the house without power if something fails on a grid-tie system. Do this really depend on a AIO system feature or it's a standard on how these grid-tied systems works? I was told RSD could be manual switch required for grid-tied. Although here...
