    ISO gasket / ideas to waterproof a roof made of solar panels

    I am looking for ideas & products to keep the area under my solar panels dry. My panels are attached to strut channels and the struts are connected to the wood framing (see photos). I don’t want to use caulking and I am thinking to overlap the panel edges, by an inch (top-to-bottom, in the rain...

    Is it safe to have the Bluetti DC Charging Enhancer (D050S) connected to my AC200MAX all the time?

    Is it safe to have the Bluetti D050S (fed by a solar panel) and connected to my AC200MAX all the time? My AC200MAX gets recharged everyday from two solar panels. I purchased a D050S to help the recharging of my AC200MAX and noticed clicking noises from my AC200MAX when the Sun was about to go...

    Bluetti EB3A Overload issue - design cooling flaw

    It is recommended for every owner to connect a (less than) 600 watt load to their Bluetti EB3A AC output (i.e., UPS mode with AC on), and connect the unit to a residential 120-volt outlet (for at least 24 hours) in order to test and see if their unit shuts down and displays an overload message...

    Is Bluetti EB3A any good as a UPS?

    There are many good reviews on YouTube on this unit and it could be a nice computer UPS replacement (compared to old fashion UPS types), however I have a 13 watt LED light connected to its AC output and I can physically see the light blink when I unplug its AC input source, which tells me that...

    Powering up procedure for charging EG4-LL using EG4 charger (48V, 18A)

    I have the EG4 charger connected to EG4-LL battery. Do I plug in the charger's cord into 120V outlet first or do I turn the EG4-LL BMS switch on, followed by closing its circuit breaker first? Thanks in advance for your reply ?

    Replacing FANS inside the EG4 6500EX-48 to make it quiet

    Has anyone looked into replacing the two fans (DA09225B12VH DC12V 1.05Amp) inside the EG4 6500EX-48 inverter to make it quiet? It seems, they are using 4-pin PWM type fans (see attached photo) and I could replace them with Noctua quiet fans but Noctua fans draw little power compared to the fans...

    Is there a quiet inverter (>2500W, 48V to 120V)?

    Is there an (>2500W, 48Vdc-to-120Vac, 60Hz) inverter that generates less than 40dB fan noise (or even a fanless)? Thanks in advance for your reply ?

    EG4-LL (48V, 100AH with display) built-in current limiting resistor

    Each EG4-LL battery (48V, 100AH with display) has a built-in current limiting resistor and I want to know when that resistor switches-in to limit the in-rush current to the inverter, and switches-out. Each EG4-LL has a separate switch for its BMS/display and a circuit breaker. Is it correct to...

    EG4-LL placed on its back???

    Is it okay (with respect to electrical and thermal operation) to have an EG4-LL battery (with display, 48V, 100AH) standing up on its back (instead of having it lay flat on its bottom, as it was meant to be placed in a battery rack)?

    Signature Solar - Freight Standard Service - 18-wheeler

    Why doesn't Signature Solar web site mention that they use an 18-wheeler for standard freight service (R&L)? My dead-end street has a turn that makes it almost impossible for an 18-wheeler to turn around. I paid more for FedEx priority freight and Signature Solar decided to do partial shipment...

    EG4 3000EHV-48 maximum 18amp PV input current

    I am not trying to pick on Signature Solar or EG4 but their manual says 18 amps max PV input current and at the same time, they have a sample table showing 2 strings of solar panels with 6 pcs in series. So, according to their own table, having 2 strings will results to approximately 20 amps...
