Exactly. More panels & more batteries. We just went through a four-day power outage here in Maryland. Our little solar power system (3 x 100 w panels) and 4 (40 WAhr) 160 AHr battery bank enabled us to keep internet up, small pump for aquariums, a fan to cool down, cell phone charging. I think now i just need more batteries to store - luckily we had bright sunshine during the 4 day outage. A few more panels from Renogy as well.

Excellent explanation. Thank you! This video fully explained the basic instructions and requirements for going solar (DIY),. In addition, I think a solar charge controller is required to have a complete solar system setup and the calculation to determine the solar charge controller amps for this video will be dividing the total solar panel watts (720 watts) by 12V (for a 12Volts system) calculation which will give us 60. So you'll need a 60A MPPT or POWMR solar charge controller.

Battery capacity (draw-down) is rarely 100% of capacity. Even if using LiFePO4 - work on 80% depth of discharge - meaning you can use 80% of 250Ah - so upscale the battery by a factor

@altuber99_athlete

Not only DoD (depth of discharge)/SoC (state of charge) should be considered, but also: • SoH (state of health). • Inverter efficiency (DC-AC conversion). • Battery efficiency (chemical-electrical energy conversion). Irrelevant. • Temperature. • Current (due to resistive losses/Joule effect as well as Peukert’s law). Specially relevant for lead-acid batteries.

In day time Sun energy will be directly used to convert electricity. But at night you will need battery to provide electricity. So it needs charging during the day time only. So it will also charge battery along with providing electricity during day time. So that additional charging of battery requires current. That's why it's added to it.

Not necessarily. A fully charged lithium battery bank could be close to 13.6V, even under load, so that could be close to 400 watts in, so a 90% efficient inverter (at that load), could indeed power a 350 watt load.

My suggestion is rather have a lot of 20 or 50 watt panels as if one fails you still will be able to generate power and replacing cost won't break the bank and don't ever place a panel as closely to the roof as a hot solar panel produce less power and fail sooner than one with adequate ventilation if possible add heat sinks at bottom of panel.

This is correct, so the selected battery of 250AH is therefore incorrect... and should be more like 400AH or 450AH, unless it is lithium... then it is correct. Most batteries will specify their max charging current and keeping it close to max charging current is best to ensure a fast charge and good maintenance of battery by keeping it topped up.

There's something called DoD, Depth of Discharge. How much Watts you can pull out of fully charged battery that you put inside the battery during charging. It changes as per Battery Chemistry and How long in Life you want it to retain. For lead-Acid Chemistry is 50-60% DoD. For Lithium Chemistry is 90-95%.

This is a very rudimentary calculation which is good to gain an understanding on paper. This type of system is not practical in the real world

@DL-kc8fc

2 жыл бұрын

@@fuzailzahid1 Yes.Therefore, this is done differently in practice. First, you will ensure the maximum size of the solar field that you can realize with your possibilities and locations. So you first solve the position of the panels and from that time the greatest production (not always the possibility of ideal settings and appropriate production time). To save money for copper on wires, you choose, for example, a 24V system or higher. This will be possible to quantify the performance and, of course, to the maximum production of amperes (A) to determine the type of your regulator. You can use a lead battery that has a depth of 50 percent. Depending on the charge and discharge time (through an inverter with the required VA performance), you can find out of the deficiency or generated surpluses to choose the capacity of the solar battery in Ah (solar battery may be more expensive than panels, regulator and inverter). At this stage it is very individual. Some use the morning production due to local conditions and leaves lead batteries with lower capacity, which act as a equalizing element. The panels supply the entire power to consumption (they have excess) and the battery slightly decreases the voltage when calling stable power depending on the collection. Weaker afternoon production charges the batteries by the next day. Someone else wants to use accumulated energy at night, so they choose a type of battery in Ah so that there are no daily surpluses. Simply all the performance of the daily production stores in the battery that is designed for it. Then it is necessary to consider poor energy production if the sun is behind the clouds, which is more than sunny days. In practice (in continuous operation), this is difficult to solve. Battery with higher capacity will not fully charge and batteries with lower capacity, even if fully charged, do not provide longer power time even with the help of panels that produce very little watts. Only from this is the purpose, not the theoretical calculation, which is only general and to ideal conditions.

@DL-kc8fc

2 жыл бұрын

@@Cr1z4n63L It depends on the battery capacity and depth of discharge. For example, a 12V 100Ah lead-acid battery will provide a theoretical output of 1.2kWh (more when short-circuited), but since the depth of discharge is generally 50 percent for lead-acid batteries, in practice this battery can provide 600Wh. Traction lead batteries can be discharged to a depth of up to 70 percent. Lithium batteries can be discharged to a depth of 90 percent. If the lead acid battery is new, it is possible to monitor the depth of discharge through the voltage when it is not under load. For example, for a 12V lead-acid battery, 50 percent is equal to 11.8V. It is possible to discharge a lead-acid battery even to 10.6V (under load), but at this value the regulator switches off the consumption so that the lead-acid battery is not destroyed.

Could you make one for 5kw off-grid setup?

A good start, but, as noted below, you didn’t factor in battery draw down. Nor did you consider things like solar panel efficiency, hours of daylight, inverter and other system inefficiencies.
