  • Shout out for Current Connected

    Hey all, Just thought I'd give a shout out for Current Connected. I bought (4) of @HighTechLab EnerAmp 170AH cells. They were received quickly and all packaged nicely. Unfortunately, there was damage to the box during shipping and one of the studs was severely bent and broke loose...
  • IBC Tote as a ballasted ground mount solution?

    Hey everyone, I'm discovering that my small 3 panel array is becoming quite a dilemma for a ground mount... Due to the rocky ground, I can't sink any posts or sonotubes. So I'm thinking I need a ballast solution. Been looking at the Integrarack as well as the powerracks. However, those...
  • First Charge/Top Balance charger issue

    Hello all, I purchased (4) 170AH EnerAmp batteries from Current Connected and an OverKill BMS in order to create a 12v battery pack. My plan was to put cells in series (with the BMS of course) and charge up with my Noco Genius 10A charger. Then put the cells in parallel (no bms) and do a Top...

    Hey all, So I want to use Anderson SB175 quick connects for making my battery mobile between home and our off-grid cabin. (Side note: I've also been eying the BigBattery 170AH power block as well, which also uses SB175). It appears that the largest cable that connector supports is 2 Gauge...
  • Burnt up junction box

    Hi all, I have my (2) 335 Watt Solar Panels mounted on the side of my garage. I used a Cutting Edge Power Entry Housing (https://www.amazon.com/gp/product/B07MMWKR29/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) to bring the wires in through the garage wall. Inside the garage, I used a...
  • Battery Low Temp Disconnect?

    Hey all, Been thinking... If my low temp disconnect kicks in on the battery, isn't that the same as disconnecting the Charge Controller from the battery? And if so, isn't that bad to do to a charge controller? (IE: disconnect battery while the solar panels are still connected and charging)
  • 24v panel into Jackery 1000?

    Hi all, I'm really interested in the Jackery 1000 for carrying back and forth between home and our off-grid vacation cabin. I have (2) 24v 255w panels (one at each location) with open voltage of 38v. I know this is too high for the Jackery's input. Is there something that can be wired in...

  • MPP Solar "premature float bug"

    Hey all, So I assume from searching the forum (as well as a general google search), that the so called "premature float bug" still exists with all MPP Solar units. Question: Is this as big of a deal if using LFP? Or is it more of an issue with Lead Acid? And does it apply only with solar...
  • MPP Solar "Overload Bypass" confusion?

    So as the title states... I've read some conflicting/confusing information regarding the overload bypass function (#23 on the 12v model) Watching @Will Prowse video, I see the overload bypass worked as expected when he started the 1500W heat gun. If I recall, it also switched back to battery...

  • Samlex EVO 4248?

    Hi all, Is there any reason to believe that the new Samlex EVO 4248 split phase inverter would not be able to start my 240v deep well pump? (I realize I'll need enough battery to handle the amps. I'm leaning towards the EG4 PowerPro (200A BMS). Is 1 enough?) Background: Well is around 500'...
  • MPP PIP-1012LV-MS Voltage Reading Problem

    Hey all, I've been playing around testing a new PIP-1012LV-MS... It is having a problem reading an accurate voltage from the battery. I have it connected to a 100AH Zooms battery and AC input (No solar at this time). I'm using all of Will's settings (except I changed the voltage switchover...
  • 2nd AIO vs. Chargeverter

    Hey all, I'm thinking of powering a critical loads panel from a 6000XP AIO. However, due to logistics and wiring, I don't want to use the AC in. I'd rather charge the batteries separately from AC. Originally, I was thinking of using the chargeverter and rigging up a relay to turn it on and...
  • Longer Positive Cable to account for BMS?

    Hey all, I'm looking to buy cables for my DIY LFP battery to connect to my busbar. (Have intentions of adding a 2nd battery later). My first reaction was to buy (2) cables (pos & neg) of the same exact length. However, my OverKill Solar BMS has 1' long cables on either side of it. Should my...
