Why are 24 volts LiFePO4 batteries a lot more expensive than buying two units of 12 volts version of the same battery brand for same AmpHour capacity? For example, on most e-commerce websites that sells LiFePO4 batteries, a 24 volts 200Ah is about $1,800 but the 12volts 200Ah of the same branch...

What will be the effect if I combine separate solar strings facing different directions on a single charge controller? Will I get the average of both outputs or less? The orientation of my roof can only allow me to separate my arrays. Please advice. I have 6 units of 330 watts solar panels and a...

I want to implement a 3-phase off-grid solar inverter and battery backup system that will run a 3hp Air Conditioner and a 2hp data center for 15 hours after power outage per day. I want to use multiple inverters connected together. The electric power scheme for my country is 230V 50Hz. I also...

I just procured two pieces of 24volts 200Amphr LiFePO4 batteries for my 24 volts solar system that includes a Midnite solar classic 200 charge controller and an Outback VFX3024E inverter. I will be connecting the two batteries in parallel for a resultant nominal voltage of 24 volts. I understand...

I want to install a DC breaker (200 Amps) between my 450Amphr 24 volts battery bank and my 3000W inverter. The type of breaker I have available is the MCB type. I don't know which of the terminals of the breaker should be for the battery and which should be for the inverter. Should the upper...

I just connected my Midnite solar classic 200 charger controller to my Outback VFX3024 inverter. I want to start with setting the charger parameters on the charge controller. How do make sure that the inverter's charger does not clash with the charge controller? I.e. how do I set priority for...

I am trying to setup my Midnite solar classic 200 charge controller. I want it to output 75 amps to charge my battery (my battery bank is big and my brand can handle faster charging). I however discover that the output terminal can only accept a maximum of 16mm2 wire (5AWG) which theoretical has...

Can MOES Automatic Transfer Switch be hacked to work with a timer to execute the transfer logic configured in addition to the voltage sensing or bypassing the voltage sensing? How can this be done?

How does MOES Automatic Transfer Switch sense battery voltage when the batteries are already connected to the charge controller? In other words, how does it discern (or differentiate) the actual voltage of the battery bank from the higher voltage supplied by he charge controller?

Can I use Schneider breaker A9N19825 as DC breaker?

I want to install a Midnite solar 150 charge controller with six units of 300 watts solar panels and connect them to my Outback VFX 3000W 24V inverter. My house is connected to the grid. However I want to give my energy production higher priority over the grid in order to recoup value from my...

I have a china made 2400 watt MPP hybrid inverter (with embedded PWM charge controller). It has a default battery charging algorithm for Lead acid batteries (gel or AGM) but it doesn't have a charging algorithm for LiFePO4 batteries. I intend to procure new LiFePO4 batteries to replace my lead...
