Higher voltage less amps. This can favor the 48vDC to allow for smaller cable for heavier and more loads. 24vDC however is a bit less cost to get into and a bit safer to work with. Some folks that have gone the 24vDC route (I am one) can feel trapped by the sunk costs preventing easy switch over...

Well heck, I just purchased a Ampinvt 24vDC, 5000w split phase inverter charger. They had one for special sale of Used -Like New on their website for such a good price ($460 with free shipping) I decided I could not pass it up. I had been thinking of having a 240vAC split phase supply for those...

I have no idea if it is reliable or if it would last. I just know from the measurements for size of the fold-able panels that the 120w rating is likely to be accurate. Not a small thing for many of these portable kits. One thing I am not sure of is if the pictured USB power converter is...

Uh no.. The input to the AIO from a 120vAC source would work to charge from is the gist of my request. If a 240vAC input was available it would work normally. I agree it is a Unicorn until someone makes it. My thread here is a shout out to the void to see if any Solar inverter company is...

The first thing I would check is all your connections. Having voltage unloaded does not always tell you if a connection is good. Summer with subsequent heat cause materials to expand and could contribute to a poor connection issue.

Just got done adding some new panels and my budget is a bit depleted. Unfortunately I start paying for medicare next month and I lose $175 from my monthly worthless old guy pension payment. May be awhile before any other purchases can be made. I will just have to wait and see what the wind and...

It doesn't do what I want. Victron, while fine equipment, lacks the features I mentioned in my first post. It is only split phase when you combine 2. It has no integrated SCC's, no control panel on unit for settings and is lacking off grid certification.

Thanks to the internet there is many places you can find information. For instance if you Google "Fundamentals of heat transfer" there are many resources including videos and books. Or you can search "understanding Solar Energy".

Ack! Victron. Only cost you your first born child (heck with arm and leg costs). Being an old solitaire, that never reproduced, I lack the necessary child.

Sure it is. You can feel it can't you? If it was gone immediately the panel would not get hot. Does it dissipate due to transfer to the environment? Yes. Eventually all heat does this. But for a while it is stored. People use thermal mass to attenuate and store heat for longer periods. It don't...

Potential energy the unloaded panel gets from the sun's energy is stored as heat. Walk out and put your hand on a unloaded panel in the sun and you can feel it. Heat is not convertible by the panel to electricity so it does not contribute to anything other than warming up the surroundings...

Based on size of panel I would estimate it is 25-30w. Thus about 2-2.5amps max charging a 12vDC battery. Hard to say what your fan is without an amp draw or wattage rating. A 7ah battery may not have enough to run it for more than a hour. (75w fan) One question I have is the hookup of the fan...

Spotted a company selling some split phase AIO units that operate off 24vDC. https://store.tumo-int.com/ They have one at 2kW and another at 3kW. Never heard of them before but they seem to have a line up of wind turbines, various SCC with MPPT, Inverter chargers, hybrid AIO and grid tie...

All things can be dealt with for more money. But a simple specification on maximum amount of panel wattage in the manual is essentially free.

You have to insert the wire with crimped on terminal fully until it clicks into the body of the MC4. If it is not fully inserted it would be very difficult to attach the cable gland and screw.

My theory is Duty cycle. It is one thing to run at 100% for a couple of hours. It is quite another to run for a lot more hours at full capacity. Being massively over paneled can result in the SCC being unable to last.

You need to understand energy transfer. The sun provides the energy. We average this at highest production to be 1000w per square meter of area. Solar panels take some of that energy and convert it to electrical power (the amount they can utilize is called efficiency). Thus if you have sunlight...

Yes there are inverter/chargers that would handle your needs. Likely anything 3kW upwards. From the list of your loads it appears that it could be just a 120vAC model. To charge your battery from PV, wind, or hydro will require an appropriate charge controller. To grow your system simply would...

Does any of the handymen you know have basic electrical knowledge and trouble shooting skills? Without either you or them having this it is just about impossible to remotely figure out what your system needs to be operational again.

Your original question was answered. If you wish to learn more about solar the Forum here has many resources you can look through as well as simply asking. Incidentally it is always a good idea to read the manual that comes with any equipment you buy. It should tell you proper procedure for...

If you do not entertain the idea that you might pay his asking price than a meeting is a pointless thing. I hate people that throw low ball offers at me when I am selling something and they waste my time by not telling me ahead of what they might pay. Dickering over the price is a understood...

You do not want to totally discharge them. That would mean you could not restore the chemical state by recharge. Yes you can take them down to the point that not much chemical reaction is happening but lower than that is a inert battery.

PV panels without load only produce voltage. We call that Voc (Volt open cell). This voltage amount is higher than Vmp (Volts max production) which is the panels voltage when it is creating power under an amperage draw. The amperage rating of the panels is a similar thing Isc (Current short...

It is not the matter of being able to absorb the PV energy as much as it screws the logic of the controller that uses the battery voltage to set proper charging conditions as it powers itself from the battery. Disconnecting the battery removes battery voltage, being fully charged does not...

I would guess they demand he stop using another source of electricity and shut off his meter if he failed to comply. It would be within their right to do so.

Perhaps not but I would read the agreement carefully and if that sentence is not modified elsewhere I would take it as it reads. People all too often agree to things and do not understand what they are agreeing to or think it won't ever apply (that would be mean) to them.

I don't. The words are there and though his CoOp may not enforce them it always leaves open the possibility that they can. Never minimize a Contract that you agree to. It can end up biting you in the butt. Certainly he can use the CoOp power during his construction phase of everything and most...

Likely you can run more than 4 panels in series. You will need to look up the max Voc specs for the 6000xp. For example if they are typical 100w panels they will have around 22Voc. In series that adds while amperage remains the same. Microinverters are grid tie. They only work when they can...

Yes it sounds like if you agree to their terms that you can not supply any electrical power yourself. It may not be enforced for emergency power situations since Electrical energy from them was not available. But otherwise it is pretty cut and dried.

The panels output higher voltage than 12vDC your SCC reduces it to battery voltage. I have arrays of over 2000w running on 10awg that almost never exceed 10a. to the SCC. Most 100w panels Vmp is 18 volt DC. Thus 5-6a. BTW as Robbob mentioned if you wire in series you still would have only...

A few errors. 1- 100 w panel does not output 20a. It is closer to 5-6a. You do not need 8awg wire even if you add another panel. 2 -100w panels will still be below the 20-25a capacity of 12awg. Skip the Epever and go for a HQST or Sky Blue.

Load should not change output voltage. Individually the AIO's would fault if voltage is outside a value such as (+/-)5%* from inverter set point. * the manual for my PowMr 3kW list this amount in the Technical specifications.

I have been running HF in the AIO's I have been using without problem with startup surge for things. I suspect it is because 3000w (6000w surge) provides a good leeway for normal 120vAC plug in items. I also suspect that many folks fail to provide a suitable DC connection with plenty of battery...

So are disconnects, DC fuses and other components. The higher voltage of 48vDC nom. Lithium at around 58vDC has made it a bit of a scramble to find items that can properly handle that voltage.

Yes, for small off grid setups a lower PV Voc of perhaps 150v would be good. The older ones of only 100v Voc were a bit limiting even with RV style panels. 6-100w panels at 22v than could than be series connected.
