  • Anybody use these stand alone MPPT micro- inverters: VEVOR 1200W MPPT Waterproof Solar Grid Tie Inverter DC to AC 110V

    Item: VEVOR 1200W MPPT Waterproof Solar Grid Tie Inverter DC to AC 110V https://www.vevor.com/grid-tie-solar-inverter-c_10762/solar-grid-tie-micro-inverter-dc-22-50v-to-ac-110v-compact-pure-sine-mppt-p_010970615651?v_tag=f301cc40-8778-11ed-80b6-079a1a81c6c8.3 I've seen others that look...
  • Need fuse holder recommendations and bolting guidance

    I've seen other postings for MEGA fuse holders and I need to upgrade my holder. Issue: The terminals are getting too hot, yes it's an inexpensive Amazon model. The other posts were more along these are the options, and I'd like to hear how people actually like their holders as far as quality...
  • Micro Inverter to heater element

    There are some microinverters on the market that allow for up to 4 solar panel inputs that are designed to supplement energy usage or supply a dedicated 120v load. I've been going around and around about PV to hot water heating and I'm wondering if this is a viable solution. The input would...
  • Upgrading grid tie inverter to add storage: help with dual 200a service panels

    I have dual 200A service panels in my house. My two 5Kw inverters are in the garage, about 100' from the service panels. Each inverter feeds a 30A breaker in a service panel. I'm looking at upgrading at least 1 inverter to add some bateries, leaning towards Sol-Ark. However, their 8K is...
  • Solar Tax Credit : After install tree trimming

    Has anybody claimed the cost of tree trimming after a solar install? I installed my ground mount system in 2018 and since then the pine trees have grown taller. They are in a line about 120' from my array. It is impacting my winter generation so I think this would fall under site preperations...
  • Alternative grid interactive hybrid inverts? NHX, Hoymiles, Sungold?

    If anybody has any real-world experience using any of the following grid interactive/hybrid inverters with current transformer monitoring to limit export, I'd like to hear your input. NHX: https://watts247.com/product-category/inverters/nhx-hybrid-series/ Hoymiles...
  • When does Aims Inverter/Charger start charging battery?

    I have a 12V to 240Vac Aims Inverter Charger (PICOGLF40W12V240VS). The unit is set to prefer batteries and runs flawlessly to power a deep well 1.5hp pump. Sometimes, the batteries get to a low state and the Aims charger will kick on and charge them from the house. Normally charged from a MPPT...
  • Tips to find the rafters?

    Any tips or tricks to find rafters under an asphalt roof? I have a roof area that I can not access from below to find the rafters. I already have the racking and have installed it before, but I could access the underside in my shed to determine rafter locations. I think I saw something about...
  • Planning for the future - String inverters > Hybrid

    I have a 13Kw solar array feeding two, 5.0 SunnyBoy grid-tied inverters. Each inverter has 3 MPPT inputs. Two inputs are strings of 8, 325W panels and one string of 4, 345w panels. Each inverter feeds an electrical panel (I have 2, 200amp panels). The two panels are tied to the same...
  • Series battery at different voltages?

    I just upgraded my inverter from 12v to 24v to better handle my well pump. The batteries were arranged in parallel: AmpereTime 12v 200ah Plus models with a 200a BMS. They have been in parallel for 6 months. Upon disconnecting they both read 13.34V so I put them in series and programmed the...
  • What do you use to clean a sticky pollen panel?

    Here in GA, now that the pine pollen is coming to an end, I clean my panels. Its always a pain trying to get the pollen residue off. I normally soap down and scrub with a long handled brush and its wearing me out. What chemicals are safe to use on panels to help loosen the pollen goo?
  • Charge vs. Float voltage: What if MPPT only has charge?

    Ok, I'm striking out on google search. What exactly is float voltage? Its slightly higher than 100% state of charge, but less than the charge voltage. If my AMPINVT MPPT-60A only has a manual charge voltage (no float option) set at 28.4v, do I care for my 24v Lifepo4 battery?
  • Determining Payback & adding storage

    So, my power company has slashed their purchase price for my electricity down to $.04/kw. I'm grid tied and they meter on an instantaneous value, so I now buy for $.13 and they buy my excess for $.04. How do I go about thinking of adding storage and the cost benefit of it? Setup: 13Kw of...
