    MPP PIP (5048GK / MGX or MAX) Do they feed the Grid or not (or just a little bit) ?

    Se several post I found on other forums indicate that the high PV voltage models (>400V) of MMP PIP converters do under certain circumstance feed back into the grid. As far as I understand when the AC OUT side load for whatever reason drops suddenly, some burst are fed back. Based on that I...

    Pouch Compression wiki review

    IMHO following is not very clear: "Below 72°F the effect is linear. Over 72°F the effect becomes exponentially negative." Does the "exponentially negative effect" refer to the capacity fade that will become bigger over 72°F ? Or to the effect of compressing ?

    Hello from Switzerland/Paraguay

    I have been back forth between Switzerland - Paraguay the last 10 years staying there up to 8 months at times. Now the point is reaching to make a more final move. It has been an adventure. Some challenges but for me personally over all it is pretty cool. I like to build and experiment...

    Hello from Switzerland/Paraguay

    Hello All I' from Switzerland and planning to move this year to a rural area in Paraguay. I will be building my main place with shipping containers and want to add a solar system. At this location I have grid access, so very likely I will go with a hybrid system (hybrid sources, no grid back...

    MPP PIP 7248-MAX: solar input (8000W) vs charger (4860W) question

    Thx for the clarification. I didn't realize its 2 MPPT means input & output.

    MPP PIP 7248-MAX: solar input (8000W) vs charger (4860W) question

    Hi Snoobler Thx for your answer. I think I get that part of the spec; the PV input. So now 8000w total are coming in, but it can only put 62V * 80A = 4960W into the battery ?

    MPP PIP (5048GK / MGX or MAX) Do they feed the Grid or not (or just a little bit) ?

    Hi I'm planning my own system in a rural developing country location. I grid available and I would like to use it for load and battery charging when Solar is not enough. But I DON'T want to feedback to the grid at all. My understanding was that the MMP PIP models (I'm interested in 5048GK, MGX...

    MPP PIP 7248-MAX: solar input (8000W) vs charger (4860W) question

    Hi Looking at the MPP PIP 7248-MAX specs, they both offer 8000W solar input and max bulk/float charge of 62V at max 80A = 4960W I'm struggling here. Does it mean this inverter wouldn't be able to use the full potential solar gain (8000W) for charging the battery when no load is present ...

    Anyone have experience with Elfeland Aliexpress cells?

    I'm also wondering whether anyone has experiences with them. They offer right now 271AH cells (3% less then 280AH) for 17% cheaper then their 280AH cells for only 198$ shipment to Switzerland (32 cells !)...
