Understanding Off-Grid Solar Power Setups
foreign hi this is David with Santan solar your One Stop Shop for all your solar needs today we are doing the video that is about our off-grid solar power setups now we've already discussed about battery sizes how many panels uh what's your what's your power needs are going to be and then we move on to charge controllers and then from there we need to have inverters basically all your off-grid solar systems you're going to be needing some way to take that DC power accumulated from the PVS to AC power so that you can run your appliances like your TV refrigerator microwave coffee pots charge controllers computers what have you
The Essential Role of Inverters
once we decide on the charge controller that we need this is what's going to be then attached to your battery bank which will then attach the battery will attach to the inverter but this is important to get your battery charged so that your inverter will work more efficiently
Types of Inverters: Standalone and Hybrid
this is the typical Standalone inverter it's only job is to go ahead and take your battery convert it from DC power to AC power that's its only job to do make sure it's matched to the proper voltage this particular one is made for a 12 volt battery bank and we'll be talking about that how to size this to the size the right size battery bank now not all inverters will be Standalone a lot of systems come what they call hybrid inverters these particular inverters of different voltages just like the standalones this one would be a 48 volt this one's a 24 volt the difference is between this and a standalone is that it also has a charge controller an inverter built in these both are called hybrid inverters because they do both jobs of your charge controller and just stand alone all in one package again you still have to match these to the proper battery size
Inverter Functionality and Battery Compatibility
System Components and Matching
now we've already discussed earlier that there are several kinds of inverter types this being a charge controller these are modular charge controllers work in conjunction with Standalone inverters these are hybrid inverters these both have both components built into one they operate in the same methods just fewer wires and fewer connections that are necessary they still have to follow the same criteria of having to match these up to the proper sized battery bank
Specific Voltage Matching Examples
so for instance this one is a 48 volt inverter that means it has to be connected to a 48 volt battery Bank this is a 24 volt hybrid inverter this one does have to be connected to a 24 volt system this is a standalone the Standalone itself is a 12 volt so you have to have a 12 volt battery Bank attached to this one in order for it to do its job of converting DC to AC power
Battery Charging Mechanisms
now as far as battery charging is concerned people say well how does it charge of batteries well Standalone inverters do just one job it takes the DC voltage from your battery bank and converts it to AC power for your appliances that's all it will do it pulls the DC current and voltage from your battery Bank the charge controls can be regulated what goes to that battery Bank this will only give you the AC power these will do the same thing however they do manage the battery as well as PV inputs and do walls all the work that modular systems do
Monitoring, Protection, and System Sizing
Advanced Monitoring Features
as I talked about earlier there are some hybrid inverters such as such as these or other larger systems will allow you to monitor what your AC output is and what uh your battery Bank your rate of discharge how much your PV is doing and all that these that's what these will be doing for because they do have a little monitor that does both jobs in something like this that's modular usually you can get most of your information based out of out of your charge controller either through remote display or it is an app on your phone it can monitor what goes to your battery and how much load it's pulling
Essential Safety and Protection
so all these devices with the exception of the charge controller but your inverters themselves always have some sort of protection uh over volting over overloads and what have you if it over volts it'll have a warning and shut down same thing goes with the hybrids remember these both have inverters built into them just like this these will do outputs of the AC power just as well as this they do have surge protection and they also have a safety built in so if there's an over voltage or overpower overheating what have you they do have the safety measures of shutting down and protecting your system as well as a user this is a good safety concern and these units are really well made to prevent such errors
Determining Inverter Power Requirements
and once we've decided as to what size how much power you need we've already done our audit we know what we want you know how much power we're going to require you want to make sure you match your inverter to that size this particular one is a 3000 watt Standalone inverter this one is a 2400 watt this one is a 3000 watt these will also accommodate for your appliances that means that you make sure you have a large enough inverter as well as hybrid inverters make sure it's large enough to accommodate your appliances and your loads just make sure the battery Bank matches up your battery capacity is capable of handling that and for the draw that's going to be pulled from the inverter
Importance of Seamless Integration
seamless integration is important for all these and most of these units in fact all these units will work with integrating to your other services we always want to make sure that we are going to be able to supply our AC power that's the lows we're going to be using to run our appliances on our lights and to run various equipment that we may have the sustainability of these units are that they will be working to do that for you they take that DC power that your panels will deliver and or generator if you do have a generator that you hook up to these things you have to look at that as well you want to keep in mind that the inverters that you you get are going to be made it up to the right size power that you require just make sure that it is in the right size sometimes a 3000 watt may be adequate 2400 watt might be adequate some people might need 6000 watts in order to run their equipment so make sure that you are using the inverter that is compatible with your charge controller if you're using a modular unit or if you're going to be sizing your hybrids making sure that their size to the power requirements that you have

Frequently Asked Questions
Q: What is the primary function of an inverter in an an off-grid solar system?
A: Basically all your off-grid solar systems you're going to be needing some way to take that DC power accumulated from the PVS to AC power so that you can run your appliances like your TV refrigerator microwave coffee pots charge controllers computers what have you.
Q: What is the difference between a Standalone and a Hybrid inverter?
A: The difference is between this and a standalone is that it also has a charge controller an inverter built in these both are called hybrid inverters because they do both jobs of your charge controller and just stand alone all in one package again you still have to match these to the proper battery size. Standalone inverters do just one job it takes the DC voltage from your battery bank and converts it to AC power for your appliances that's all it will do it pulls the DC current and voltage from your battery Bank.
Q: How important is it to match the inverter to the battery bank and power needs?
A: You want to make sure you match your inverter to that size. Make sure it's large enough to accommodate your appliances and your loads just make sure the battery Bank matches up your battery capacity is capable of handling that and for the draw that's going to be pulled from the inverter. You want to keep in mind that the inverters that you you get are going to be made it up to the right size power that you require just make sure that it is in the right size sometimes a 3000 watt may be adequate 2400 watt might be adequate some people might need 6000 watts in order to run their equipment so make sure that you are using the inverter that is compatible with your charge controller if you're using a modular unit or if you're going to be sizing your hybrids making sure that their size to the power requirements that you have.
