    Funny story about the east-west panel spread-out idea

    OK, to get to the point here you will not get some “spread out of power production” by pointing your panels direct east and west. In summary the sum of the gains in the morning for the east panels plus the sum of the losses in the morning from the west panels equal the same production curve...

    Where the "ChargeVerter" name comes from

    In order to get over 1500w of 48v power before people had to get a dedicated inverter like a 5000es to charge their batteries, in several systems that had this the guys and I would refer to these dedicated charging inverters as "Chargeverters" Just saw the question 100 times and had to put...

    EG4 only uses DC-rated breakers.

    EG4 products are UL tested and rated by other NRTL labs as well. no pass would have been granted with AC-only breakers in use we have posted videos of them tripping with DC in the appropriate time. EG4 has never used AC-Only breakers on batteries Threads or comments implying otherwise are...

    Best portable grounding ideas

    Guys, have some friends looking to have a high joule fence charger that they want to move around. Typically calls for 2x6ft ground rods Are there any grounding kits out there with multiple small rods that add up to that and the assembly can move easily?

    Schneider XW Pro 6.8kw insane load test

    Putting more than 8kw on an EG4 6500ex

    This question comes up a decent amount, since the mppt is power-limiting what would be the harm with using more solar, like 12kw on a single 6500w unit if you have it? The units will initially work alright if you keep the VOC limit minded, you could use 30kw and you would work fine for a good...

    New EG4-LL battery: Diesel Fire put out by internal fire extinguishers in the

    We actually put a diesel drenched rope in it first, then had to up the temp by pouring more diesel in and dropping in the rag. A class D fire extinguisher was on hand to put it out if an issue had started thermal runaway. This is not covered under warranty LOL

    We did a load test on the new EG4 6000EX inverter

    Just a couple notes: -The loads on the 2 unit parallel test were not blind unbalanced -The one unit test was run long enough to demonstrate continuous capacity Let us know what the team could go further on next time if y'all get any ideas

    UPDATED: Issue #1: neutral-ground bonding, we have had these units ship under the American version, The PCB is not the same, some others here show removing the screw bond, but then find that the board still has a conductor trace that leaks to ground. This is why you need to buy these from an...
