vta2008: They are playing safe, usually cos majority of owners arent so knowledgeable or the installer himself. The weakest link is usually the battery... A dry iron consumes btw 800watts to 1400w, whilea steam iron between 1600w and 2500watts. Now if you have 4 batteries, you may escape damage to the batteries if using dry iron. Of stated wattage range above., But steam iron will likely damage the battery. Always have the c/10 rule at the back of your mind when using leadacid batteries. Lithium batteries on the other hand has no issues with load and can do 1c, though 0.5C is the norm. C in this scenario is capacity of the battery in AH 3 Likes |

earthrealm: The pressing iron uses around 850W max according to my wattmeter. The 4 pieces of tubular battery are setup to make a total of 24V 440AH. Do I apply the C/10 rule per battery or the entire setup? Thanks NOTE: I mainly use the dry pressing iron and oven when the solar panels are at their maximum output of about 800W |

Re: Solar Energy, A Complement To FTA by earthrealm(m): 4:02pm On May 03, 2023 |
vta2008: the c/10 is same where you apply it singly or cumulatively. c/10 of 440ah is 44amps, so you shud try to keep ur total running load below this at sundown/no sun periods...multiply this by the system voltage to get about 960watts. ie 24v x 44ah. the iron of 850watts wudnt damage your battery.....i even use a steam iron of 1200w on my 4 flooded batteries...no issues. this is because the thermostat of the iron regulates the load..heats for 60secs or so and turns off..n cycles again. am sure the battery might hv gotten damaged, if it was a constant 1200 watts draw..like sumo/ac etc. pls the quality of battery plays a big role as thicker plated batteries are more durable. 2ndly flooded batteries are tougher n recover from abuse better than the normal dry cells. find below my ranking of batteries lifepo4 >>> 2v 600ah and above cells >>>>>> flooded battery/AGM >>>>>>>>>Other sealed battery types 1 Like |

Juror: This last part is the reason why i have never bothered to patronize our local sellers here flooding the forum daily with their adverts without any meaningful contribution to this body of knowledge. They promise and sweet talk but once money has changed hands it turns into a different ball game entirely. For those of us up country, who do you turn to for help ? Yes, i can listen to "some" recommendations from reputable users with long term history and reputations to protect but last last the risk always lies on your head. The fact that a seller needs to always go and get stuff from other sellers and doesn't have a shop with stock is a red flag for me. Trust is rare these days especially for us in Nigeria which is why your better off sometimes buying directly from the retailers/dealers rather than middle men adding up costs to make a buck. 9 Likes |

Hello house which of these solar panel charge batteries during rainfall, Monocrystalline or polycrystalline. Thanks 1 Like |
Re: Solar Energy, A Complement To FTA by contease(m): 6:12pm On May 04, 2023 |
temitimx19: "Open sidebar Solar panels and batteries. User which of these solar panel charge batteries during rainfall, Monocrystalline or polycrystalline. Thanks ChatGPT Solar panels, whether monocrystalline or polycrystalline, generate electricity by converting sunlight into electrical energy. However, during rainfall, the amount of sunlight reaching the solar panel is reduced, which can affect the charging of batteries. Therefore, neither monocrystalline nor polycrystalline solar panels can directly charge batteries during rainfall. However, if the solar panel is connected to a battery storage system, the battery can be charged during periods of sunlight, and the stored energy can be used during periods of reduced sunlight or rainfall. It's worth noting that polycrystalline solar panels are generally less efficient than monocrystalline panels, meaning they produce less electricity per unit area of solar panel. However, the difference in efficiency is typically small and may not significantly affect the ability of a solar panel to charge a battery in varying weather conditions.

In trying to understand what 50% DoD for a 24v norminal system in Volts... Eg, from 29v to 20v, 21v,22v,23v or 24v use? considering that at rest, a Lead Acid battery would always drop to 26.xV without trickle charge (Float), I got this unsatisfactory info: "Open sidebar 24V Battery Depth Discharge. User what is 50% DoD for a 24v norminal system in Volts... Eg, from 29v to 20v, 21v, 22v, 23v or 24v use? considering that an rest, a Lead Acid battery would always drop to 26.xV without trickle charge (Float) ChatGPT If the nominal voltage of a 24V system is assumed to be 24V, then a 50% depth of discharge (DoD) would mean that the battery has discharged half of its capacity, which would equate to approximately 12V. However, it's important to note that the voltage range you provided (from 29V to 20V) is a bit wider than what would typically be expected for a 24V battery system. Additionally, the resting voltage you mentioned (26.xV) would likely only be applicable after the battery has been fully charged and then allowed to rest for some time without any load or charging. In general, the voltage of a lead-acid battery will vary depending on a variety of factors such as temperature, charge level, and load, so it's difficult to give a specific voltage range for a 50% DoD without additional information about the specific battery being used and the conditions under which it is being operated.
