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...
THHN is not weatherproof
THHW is weatherproof
XHHW is weatherproof
codes:
T.......thermoplastic
X.......plastic, unsure of variety but not thermoplastic <edit> crosslinked
H.......Hot..... 75deg. c.
HH... Hot,Hot....90 deg C.
N......not weatherproof
W........weatherproof

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...
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...
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...
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
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...
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...
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...
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...
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...
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
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

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...
My system is made in the America,s....(mostly)

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.
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...
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.
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.
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
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...
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.
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...
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...
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...
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...
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...
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...
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...
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...
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...
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.
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
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...
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...
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...
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...
Here is a crimper that gets err done, its made in China like most of the others BUT.....the dies have been redisgned by an american engineer to fit the lugs that we use here which are very much thicker than the asian ones.
This is marketed by TEMCO.......Tower Electric Motor...
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.
