    That's a slick system you have there! I like it a lot.

    Is the white material sheets of HDPE? Are you clamping the cells with it? They look nice and snug in the housing. Looks great!

    Tigo Optimizer Open Circuit Voltage

    Thanks for showing me those, I hadn't seen these before. Is there an existing discussion regarding these chinese optimizers? I did a quick search and didn't find anything.

    Tigo Optimizer Open Circuit Voltage

    Yes they were used, but were cheap enough, where I'm not going to bother a return. I do have some shading issues on the 8 panel array that I newly installed. I was going to try out these two optimizers out to see how they worked, and was going to purchase more in the future if they worked out...

    Tigo Optimizer Open Circuit Voltage

    No. I have opted to just go without the optimizers for the time being.

    Any new battery dealer recommendation? Shenzhen Basen on my naughty list

    I placed my order with Basen on Oct 21st as well, and I received my batteries on Dec 1st. My Fedex tracking said Norcross, GA since the number was generated but the shipment never actually scanned through Georgia. First sign of activity on the tracking number came from Santa Fe Springs, CA a few...

    Hi Ampster, Where did you get those braided bus bars? They look awesome.

    Battery build picture thread

    I would like to see pics of everyone's completed battery banks. Show off you battery build pictures here. Here's mine made of 16 Lishen 272ah cells and an "320A" Ant BMS: This is the frame/cart I made for the battery. It's made out of leftover cedar fence boards and redwood 2x8s. The vertical...

    Adding off-grid panels and batteries to existing grid-tied system

    Just to update this thread. I got the Skybox, and new PV panels installed and online. I had to rearrange a subpanel to become a critical loads panel, and rewire my existing PV breaker into the critical loads panel. But everything is up and running. They Skybox itself was a breeze to install...

    Tigo Optimizer Open Circuit Voltage

    I bought two used Tigo TS4-O Optimizers and tried putting them on two panels (370W) for testing. I've never used Tigo optimizers before but what I've read is that by default, I should be reading the full panel voltage (40V) at the optimizer output leads. But I'm reading only 7mV on one...

    Adding off-grid panels and batteries to existing grid-tied system

    I've decided to go with a Skybox. It should be arriving this coming Monday. Also have (8) 370W bifacial panels coming too. I think I will get the panels and inverter installed and running before purchasing batteries. That should keep me busy for a little while; gotta buy/install the critical...

    Adding off-grid panels and batteries to existing grid-tied system

    Yes I am with Peninsula Clean Energy CCA which serves San Mateo County. I found the section where the application calculated my estimated generation and estimated usage. But I can not see any verbage stating "thou shall not generate more than this amount." See a snip of my NEM agreement...

    Adding off-grid panels and batteries to existing grid-tied system

    That is one heck of a post GXMNow! Lots of great first hand information and lots to think about on my end. I have a Chevy Spark EV and a Model 3. So 19kwh and 75kwh respectively. Weekdays I use maybe 8kwh just driving the Spark. The model 3 is strictly weekend duty, and then I probably use...

    Adding off-grid panels and batteries to existing grid-tied system

    Thanks for your input Ampster. I've read many of your posts. I think I am in a similar situation where you once were, with similar goals. I'm in the San Francisco Bay Area under PG&E but am still under NEM1.0. I've dug up my signed copy of the NEM agreement and I can't find where it limits...
