keeping a big solar project organized in 2025

[BigGrizzly]

Finally realizing how big of a lift this project is. I've got 57x Alexus 400W panels, Gridboss, Flexboss21, 3 EG indoor wall batteries, and a full suite of Tigo optimizers/TAPs/CCA on order. Between the sale at Signature Solar and shipping, it felt like the right time to just pull the trigger.

Plan right now is to get the inverter, batteries, Tigos, and conduit squared away over winter, then deal with the roof once spring hits. I do have an electrician helping with the main tie-in and a pre-inspection, but the rest is on me. My main concern is staying on track with so many moving parts... shading, optimizer setup, battery wiring, conduit runs, code compliance. For folks who've done big installs like this, how do you keep everything organized? Checklists? Project management apps? Whiteboard in the garage?

A big whiteboard in the garage is a great start. It's a low-tech way to create a visual checklist and project map. You can break down the project into major phases, like the inverter and battery install, followed by the roof work in the spring. Within each of those phases, you can create a detailed list of tasks for each component. Another approach is to get a project management app, like Trello or Asana, to create a digital checklist. This way, you can attach notes, manuals, and links to each task. The key is to check off each step and not move on until it's done. You've already got a good plan by doing the indoor work first and waiting for better weather for the roof work.

@BigGrizzly okay, that's a massive list of gear! My quick tip for a project this big is to read every single manual before you even start the first step. The time you spend on the couch will save you twice as much time on the roof
also, since you have an electrician helping with the tie in, use them as your main resource for code compliance. before you run any conduit or mount any boxes, have them review your plan. getting a professional sign off on the layout is a massive step towards a smooth final inspection

Another thing that’ll help is after you break your tasks down give them a deadline and create a punch list to be sure you knock out every step/phase that way you’re focused not concerned about something that you forgot about. Also look into a wire you might like to use over conduit called teck-90. It’s a rubber covered flexible metal cable that you can run through lakes and it’d never rust or rot while still being armored conductors that you can pretty much get in any configuration of wire size and number of wires inside
