  • Post in thread: Clean up: off topic conversation from another post shifted to its own post

    Very familiar with Bob Carver, I have a whole stack of Carver including the TX-11 which now has a problem with the multiplexer, so now i am using a lesser tuner but my main amplifier is the 200 watt unit with the Carver tuner /preamp. Cant remember the model numbers but I have allways...

  • Post in thread: Idle 'no load' Consumption: Specs vs Your Personal Observation

    I think that it was in N.E. Washington area, where a bunch of the really great inverter designers were. That was in the very early days of inverters along with the Trace. There was another inverter company back then that predated both the Trace and the Brutus and the designer was a sailor...
  • Post in thread: Need help please with Victron 500A Smart Shunt readings

    One huge problem that i see just at a glance, this will be changed when you get your lithiums back in service. But its a very major problem now. The battery cable lengths need to be exactly the same lengths and the same guage as each wire will have a different voltage drop depending on length...
  • Post in thread: Can I connect my alternator to my MPPT?

    The whole issue is when the tow vehicle battery if fully charged it will shut off the alternator even if the coach batteries are not charged, the alternator does not “see” the coach batteries , the solution is to use a B2B charger, this is designed to charge a battery from another battery...
  • Post in thread: Schneider Conext 4048 - Load Center set-up and Breaker requirements

    I saw that and wondered if those were crimp on terminals but looking closer I think that is heat shrink
  • Post in thread: Alternator DC/DC converter spec

    Use the Victron B2B charger without a MPPT controller in the loop, MPPT controllers are designed to use a soft source of power, batteries are not a soft source of power. MPPT controllers are buck-boost converters but they are not designed to do what you suggest
  • Post in thread: Why fuse SCC wire at "far" end?

    Correct, your statement there is true but my statement is also true, I have seen that fault and recorded it on my data logger. Are we done with this, You are putting out some good information there and I do appreciate it. There are a lot of newcomers to this arena who do need some guidance from...
  • Post in thread: Battery gravity doesn’t look good

    L-16 are build differently by different manufacturers, The solar ones are only built by a few companies that specialize in it. Interstate is NOT a battery builder, they are a battery marketer, they put their labels on batteries that have been manufactured.... Interstate L-16 traction batteries...
  • Post in thread: charging 48v battery with 24volt input

    PFC power factor corrected......when some loads draw power the current is not in “phase” with the voltage and this will result in overloading the generator due to the current leading or lagging the voltage by some power factor. The way to correct this situation is to use a “power factor...
  • Post in thread: growatt 5000 US model - grid backed up self consumption - connection to main service panel

    During U.L. certification up to 10kv. is applied to every line voltage terminal to test for lightning strike protection, This is not applied to the neutral terminal as lightning normally strikes the live conductors only , not the neutrals which are generated at the utility transformer next to or...
  • Post in thread: Schneider Conext 4048 - Load Center set-up and Breaker requirements

    I have seen crimp on terminals that have pins for inserting into terminal blocks
  • Post in thread: Magnum MSH4024RE-L stackable?

    Let me correct that misconception......... The Magnasine IS NOT two 2kw inverters.....It is a 4kw inverter with a split phase autotransformer as the output Ditto the 4kw Schneider 4 kw unit also with a autotransformer The limited output is the maximum load unbalance of the...
  • Post in thread: Midnite classic 150

    I use the calibrate function with a Fluke 87 and get very accurate voltage settings, my 2 Classic 150 are at least 10 y.o. now, nary a hitch, they just work

  • Post in thread: Need advice for home DC fridge

    Meanwell manufacturers very good AC to DC converters, this one can be used as a 12 volt power supply to run 12 volt devices, rated at 350 watts continuous https://www.amazon.com/gp/product/B07VTLJS18/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 My DC fridge draws only 41 watts at 12 volts...
  • Post in thread: Can growatt be configured to backfeed to grid when power is on?

    Dump loads are real on battery based off grid systems as well, I use Trace C-40 PWM controllers set up as diversion control to dump excess 24 volts from the battery charge cycle, 2 separate solar systems, 2 diversion controllers, 2 double element heaters divert about 2600 watts max to a single...

  • Post in thread: Educate me: 48V DC Battery Fuses, Circuit Breakers and Switches

    So exactly what happens if there is a large load on the battery bank and someone opens that breaker? As I understand there will be a non-extinguishable arc across the contacts. I scrapped the Fution powerwall due to poor quality build including AC breakers on the battery , etc.
  • Post in thread: Need help please with Victron 500A Smart Shunt readings

    Ok so I wrote that several days ago but could not post it as I took a lightning strike which took out some of my wi-fi link so a bit late and out of place. I have seen many solar system failures directly due to unequal current distribution caused by non equal battery cable lengths. This is a...

  • Post in thread: Dump all excess PV to air heater?

    Santa Cruz county...coastal...pea soup fog in the spring, Im right on the coast......The San Francisco bay area draws in a lot of coastal air to replace the hot air that they generate, resulting in some real pea soup here.
  • Post in thread: Looking for inverter with UL listed stamp

    I did a career at a huge electrical company known by two initials and we documented the hell out of everything, it was the way everything was done there, Sadly now we have throwaway junk filling the landscape.
  • Post in thread: 36 volt dc solar charge controller

    Very old systems were 32 or 36 volts as well as 40-65 foot fishing boats in the 30’s thru the 50’s but long since abandoned The large Jacobs DC Wind Generators were 36 volts, 1500 & 3000 watts, 1930‘s thru 1950’s Outback still has 32-36 volt inverters in their product line Pretty darn obsolete
  • Post in thread: What size BMS do I need for a multiple BMS system?

    Based on what has been said about Overkill, I was going to purchase my JBD from them but they never responded and they were allways backordered. I had been hearing about current_connected so I ordered from, they had the units in stock, but very shortly got a call from them about their stock came...
  • Post in thread: charging 48v battery with 24volt input

    The generator is DC........IT does not generate AC.......Transformers are AC.....NOT DC The only way to change voltage on DC is a inverter or buck-boost converter....or change the generator.....very expensive.
  • Post in thread: Affordable dc breaker or panel for blue sea a series

    I should have read twice before I responded......anyway blue seas do not manufacturer their own breakers, those are Carlingswitch A series, builders use these as well I have been using MidNite Breakers for quite a while now. They market the Carlingswitch series D breaker as the MidNite MNDC...
  • Post in thread: Midnight classic150 & Schneider 4024 good combo?

    MrM1, I saw your post, wanted to respond, but s##t happens. In reality I would like to operate at 50 deg C but my upper limit is 70 deg C , after that I feel that I am taxing my hardware too hard, I think about buying more hardware. I have a stack of gorgeous Carver Audio gear that is 25-30...
  • Post in thread: Two MPPT charge controllers in one. Any about?

    The Midnight product does have internal battery over volt protection built in which trips a breaker on the input of the controllers. It is very definutely high end teir-1 product.....200 amps output 2 x 100 amp MPPT controllers , 48 volt only, specifically meant for large installations. Made...
  • Post in thread: Dump all excess PV to air heater?

    What kind of compressor....? Not a Danfoss permanent magnet motor, My Grape Solar 5 cu.ft. danfoss powered referigerator uses 42 watts with a 15-20% duty cycle, my coleman cooler uses 48 watts non stop 4.0 amps at 12 volts (it does not have a thermostat).....and it will not freeze using 5 times...
  • Post in thread: Victron Phoenix Inverter for 240V Split Phase in USA?

    The 3 wire pump is common, start, run. very common in submersibles, the control box is up top so three wires from pump to control box, Start windings is controlled by control box up top, senses pump speed by current. Q2....No, mine does not vary in frequency depending on battery charge state...
  • Post in thread: Best equipment for ham radio (no rfi interfere)

    By far the very lowest EMI/RFI inverter is the Exeltech.......these are built for the communications industry. They are not cost competitive with cheap gear....!!! As far as low EMI/RFI from a solar charge controller.......lots of luck , except for non-switch mode they ALL emit trash on the...

    Update....just revisited the bogart site, they now do have remote monitoring via wi-fi with their adapter W-2030, It a new product that I had not seen before so now they do have a better user interface.....well done Bogart....I did suggest it Their solar charge controllers do have a place but...
  • Post in thread: UL listing and/or other certifications

    In California the state PUC (Public Utilities Commission) requires the device to be “Listed” by the certification Agency tested to UL , TUV, ETL or any other testing agency does not get it certified to UL , TUV, ETL or any other testing agency does not get it PUC will only check the listing...
  • Post in thread: Midnight classic150 & Schneider 4024 good combo?

    That is an assembled system of individual components.... It does not fit the description of an AIO....all in one. With the Growatt, Synsync, etc. you cannot remove the SCC and install a Midnite, Schneider, or any other SCC into the Growatt or any true AIO unit. There are advantages to both...
  • Post in thread: 2 x 200amp panels but only 200amp meter (not 400 or 320amp)?

    One reason that I have seen for two 200 amp panels on a single 200 amp main is that single space breakers are way cheaper than twin breakers also they have more space to dissipate heat. I have seen 20/40 (20space/40 circuit) panels that were stacked with twin breakers that were hot to touch...

    Mostly hanging in the barn but easy to connect to a dead battery on the vehicle.....no controller needed
  • Post in thread: Combiner and Breaker for 250vdc

    MidNite Solar MNPV combiner boxes can be fitted with 150 volt, or 300 volt breakers or finger safe fuses in the same voltages. the 300 volt breakers are double gang breakers wired in series but they are Listed to UL by ETL or UL, MidNite uses both testing labs to list products.
  • Post in thread: BestSun Powerwall

    Look deep down the ad, it states that these are made to order.......once order is placed you need to wait for it to be assembled.........john and freddies tinker shop.....searching there is only one name associated with the exact name of this operation
  • Post in thread: Battery gravity doesn’t look good

    Your batteries are in desperate need of an equilization. I would not trust what the EPever is telling you, they are not accurate. I much prefer true float type hydrometer but your refractometer is all you need and it tells the story. You are way undercharged..... Most battery chargers are set...
  • Post in thread: Mismatched Panels - 2 Panels Parallel to 1 in Series

    There is a small mismatch but the percent lost would be in the 1-2% range. Not enough to worry about.
  • Post in thread: Can growatt be configured to backfeed to grid when power is on?

    Oh so I am quite well aware of exactly what the codes are,.....My experience was not to feed the grid , that is of no consequence in a ”mission critical power system” the point is to always have the power you need to make the systems run. I did professional communications networks as systems...
  • Post in thread: Alternator DC/DC converter spec

    Some small controllers measure dc current from the panels on the negative dc input wire and the dc output on the negative wire so grounding both wires disturbs the controllers measurement of current. You cannot ground both the input and the output to charge the battery, My old tracer 3215...
  • Post in thread: DC Fridge or AC fridge with inverter?

    Most AC Inverters draw 20 watt idling , putting out no power at all......that’s 480 wh/day by itself.....with no loads...the best of the best...the Exeltech draws 8 watts idling ...that’s almost 200 w.h./day.....and that’s with the very rare low idle draw option which is $700 extra.....no my...

  • Post in thread: Recommended mounting material for mobile

    Diamond plate aluminum in approx 3/16 to 1/4 inch thickness measured at the smooth place, meets the code and will not burn Commonly used in ambulances and firetrucks. Inverters and charge controllers do get hot enough to combust wood.
