In this comprehensive guide, we explore the specifics of integrating and optimizing the EG4 for complete off-grid capability or grid interactivity. As a quick primer, the outdoor-rated EG4 enables roof-top solar panels to efficiently charge a 48V home battery bank during the daytime.
You can use 12 v solar panels to charge a 48V battery but ONLY if you connect the 12v in series to get more than 48V. If more then there is this magic box called MPPT controller that downgrades the output voltage from the solar panels to fit the voltage of the battery? What happens when a mppt controller fails?
Midnight Solar says +30%. A 48V battery bank will want to charge at anywhere between 50-59 volts, and for lead-acid that needs equalization, up to 64V. So, you need a panel string that is ~ 58V X 1.3X = 75.5V. So, wire your panels to put out at least 75-78V, and you should be fine.
use a MPPT boost solar charge controller that will handle the panel output, boost the voltage to the level needed for battery charging and prevent overcharging of the battery This is the low-cost version that will hopefully still yield good results. After construction and testing, I'll update you how well it works (or not).
Solar panels, such as those used in the example of Mitsubishi's 150 watt panels, have a voltage at maximum power point (Vmp) of 23-34.6 volts. The efficiency of solar panels decreases when the voltage is further above the battery charging voltage.
A standard 36-cell 12V solar panel has a Vmp of ~18V. A standard 60-cell panel puts out ~30V, and 72-cell 37.5V. A MPPT controller needs some overhead voltage above what the battery needs. Midnight Solar says +30%. A 48V battery bank will want to charge at anywhere between 50-59 volts, and for lead-acid that needs equalization, up to 64V.

So, I''m just getting into Solar. I was going to go with a 48 volt system, they''re cheaper, and from what I''ve read, generally better, you need double the batteries from a 24 volt system, but that also gives me far more battery life. However, from what I''ve seen, they appear to be more complicated as far as the solar panels are concerned.

12 · As we mentioned earlier, you''ll need to calculate how much energy storage you need based on your consumption. You''ll also need to decide on the right voltage for your system. Solar energy systems typically run on either 12V, 24V, or 48V systems, and the battery you choose must be compatible with these voltages.

The MPPT can handle even more variety from panels and batteries as well -you just would need to set it up in the app. Your PV''s will almost always have more voltage UNLESS you are using 12-18v 100w PV''s (usually they run around 22v) into a 24v (28v) battery. Then you would want to series at least 2x 100w panels to your MPPT (44v for a 28v battery).
Which batteries are best for solar panels? Solar ''s top choices for best solar batteries in 2024 include Franklin Home Power, LG Home8, Enphase IQ 5P, Tesla Powerwall, and Panasonic EverVolt. However, it''s worth noting that the best battery for you depends on your energy goals, price range, and whether you already have solar panels or not.
I have 48v solar panels and my batteries in my motorhome are 12v.

My MPPT configuration works perfectly with a 24v system, but it does NOT work with a 48v system. I would likely end up dedicating one panel to 12v production and 2 panels to 48 production using a new MPPT or by paralleling my existing 100/20s to create a 100/40. (The wizard tells me that a 150/35 would do the job.)
