Hello house, good evening. So I have a setup of 3 pieces of 250w panels on a 1.5kva inverter and 2 batteries, but it doesn't charge fast enough with the panels, I figured that it needed more panels and someone is offering me a brand new 520 wats panel at a good price, however, I refused buying cos I read that joining panels of different wattage together is not a good idea, however, I went ahead to ask my installer if the panels can work together and to my shock, he says they will work fine. I am sceptical about it and don't trust his judgment on this one, so I decided to ask the professionals in the house, what are the pros and cons of joining panels of different wattage with such wide margin? Cc - Valto brightk Iinnov8 dacool1 mctfopt and anyone that cares to help. Thank you. |
Re: Solar Energy, A Complement To FTA by odimbannamdi(m): 5:07pm On Sep 17, 2023 |
Cutezt: You need to provide more information: What are the models, type and sizes of the batteries? What is the brand of the solar panels? And what is the purchase source of the solar panels? This will help us know whether it is likely to be of true capacity as most solar panes are usually of lower capacity compared to what it is advertised as Also, what is the configuration of the solar panel connection and what kind of solar charge controller are you using? |
Re: Solar Energy, A Complement To FTA by dacool1(m): 5:25pm On Sep 17, 2023 |
Cutezt: Provide us with more information What's the voltage of the previously installed panels and the new one What kind of charge controller do you currently use. Give us the specs |

Cutezt: You still didn't state the size and type of the batteries. The type of connection configuration of the panels would also have been helpful in giving you some precise advise, so I will just make some assumptions and inference to advise you from my own experience All other things being equal and theoretically, 1 unit of 200ah smf (sealed maintenance free) lead acid battery will need at least 600w solar panels to charge optimally. This assumption becomes more significant if your batteries are tubular batteries, as tubular batteries need more intense charging. You mentioned that you have just 3 units of 250w solar panels. So, following the rule above, your cummulative solar panels capacity is 450w short of charging your 2 batteries optimally Also, if you did not get your solar panels from a credible source, there is a very high chance that what you have is a 150w (or even less) panels pasted with a 250w sticker. Again, the configuration with which your solar panels are connected plays a significant role in harvesting sunlight optimally for their true capacity. For that size, anything short of a 3-Series connection will be sub-optimal Finally, even though the full picture is not in view, I can decipher that your solar charge controller is a PWM. PWM controllers are not smart enough to harvest sunlight energy optimally. You could have gotten away with PWM if you were on one battery or had a better connection. It is best you go for MPPT solar charge controllers |
Re: Solar Energy, A Complement To FTA by dacool1(m): 8:14pm On Sep 17, 2023 |
Cutezt: I don't think this will work. The voltage of the panels do not match except you will be willing to buy another charge controller. |

Sorry my response is coming a bit late, was actually on transit. Squid actually still makes top 3 of top 10 best Cache and Proxy Servers till date. However, caching also has some drawbacks. Caching can introduce inconsistency, as the cached data may not reflect the latest changes or updates on the server. Caching can also introduce complexity, as the web application needs to manage the cache expiration, validation, and invalidation policies. One of the reasons that has slowed down the use of Cache servers in a today's internet surfing is the dynamism of data update. With the exponential rise in the use of Social Media Updates, Ads, ChatGPT, SSL enforcement, etc, it has become so important for a web server to serve current or most recent data rather than a stale data. That being said, NGINX is one of most popular open source reverse proxy servers for Linux. It's lightweight, fast, and offers a range of features such as load balancing, HTTP caching, SSL/TLS encryption, and more. NGINX is widely used by web developers and is particularly useful for serving static content, handling SSL certificates, and serving as a reverse proxy for HTTP/HTTPS traffic. NGINX is fast and scalable, making it ideal for high-traffic websites. It's also easy to configure and has excellent documentation. The only negative thing about NGINX is that it does not offer a built-in GUI interface, which may make it difficult for some users to manage. There exist several other Cache and Proxy Servers eg:, Apache HTTP Server, HAProxy, Varnish, Traefik, Pound, Caddy, Privoxy, SwiperProxy, Tinyproxy, Skipper, Varnish Cache, Nuster, Polipo, etc. Whichever choice you make from the list above, There are some options that you must consider a must have for your Cache Server which includes but not limited to: Purge cache: this allows you to refresh cached files. Some providers only allow entire cache storage refreshing. Some CDN providers also limit the number of purges allowed over a predetermined period. The effectiveness of a purging request is determined by the time it takes to propagate through a network. Never/always cache: this control allows you to manually override cache headers and tagging files that are always served from cache or those that have never been served. This control is useful in cache management, especially when used with bulk management options that allow the applications of these directives to file groups e.g., all JPG files in images/templates/folder. Period cache: this is a refinement of the always cache control. It allows you to create a specified period when the object is to be served from the cache before refreshing. Cache for period can be accessed from the CDN GUI for easy management of specific files. This is a useful option when used for bulk file management, e.g., all JS files cached for at least five days. and the list goes on. In conclusion, choosing right cache and proxy server for your environment depends on your specific needs and requirements. All of servers listed above offer unique features and capabilities that can be tailored to meet your specific needs. Whether you're looking for a lightweight server for a small website or a high-performance server for a large web application, there is always an open-source cache and reverse proxy server for Linux or other environments that will meet your needs. ojesymsym: 2 Likes |

brightk: Mikrotik may not be as reliable in high-traffic environments or may not be well-suited for large-scale network deployments. Mikrotik has limited tweaks and flexibility in terms of traffic manipulations. I didn't bother myself to make my Mikrotik box a Cache and Proxy Server because it's handling lots of things already, going from ROUTING, DHCP, FIREWALL, MULTI-WAN, etc. each time I tried to implement a proxy server with this same box, I always notice a slight difference in performance. So I intend to deploy a second box to handle the Proxying part of my traffic and maybe Hotspot Server for my staff and guests. I have to mention that Mikrotik DNS always crash because of the big static list which leads to a R/W issues. Back in the days when the x86 versions was the best option for larger network environments, R/W speed was a problem, as year went by, we had SSDs which performed better but you can't compare the performance of Mikrotik to the likes of Squid and NGINX running on it's own linux machine and solely for the purpose of Caching and Proxying internet traffic. Even though we now have more robust Mikrotik ROS Boxes and Hardwares with sophisticated configurations, Mikrotik still haven't made it to the Top 10 Cache and Proxy Server lists till date. 1 Like |

odimbannamdi: Sorry i skipped that part, My batteries are 2 luminous Tubular batteries, 220ah. and i really did not buy the equipment myself, the installer did everything based on my budget at that time but the pannels are able to get me through the day till the next day before it goes low if there is not enough sunlight. Yes, My charge controller is PWM and i dont mind buying the MPPT if the pannels will work. dacool1: If it will work, i will look at the more economical option, if buying 250w pannels to match the setup in place already or buying the 540w and a new charge controller. |
Re: Solar Energy, A Complement To FTA by odimbannamdi(m): 9:17pm On Sep 17, 2023 |
Cutezt: Throw more light on the emboldened. But based on your explanation so far, it will be cheaper and more cost-effective for you to switch to MPPT first and observe for improvements before you invest more into solar panels |

Re: Solar Energy, A Complement To FTA by Cutezt(m): 9:57pm On Sep 17, 2023 |
odimbannamdi: What i meant is that if the batteries are charged, even if it is halfway, i can use it for the entire day, i usually turn it off at night as i dont need light for anything as i sleep, but that's usually very late, maybe 1 or 2am. It takes me from the previous day till the next day, if there is not enough sunlight on that day, it goes to around 23v and i usually turn it off that time. so in summary, if charged anywhere around 25% with Light, then it takes me around 20 hours with 4-5 hours of sunlight. |
Re: Solar Energy, A Complement To FTA by dacool1(m): 10:17pm On Sep 17, 2023 |
Cutezt: Not just the wattage but voltage should match, also once you add more panels you will exceed your charge controller max AMPs. I think you will need to get another charge controller This is what I would recommend, get the 520watts panel with a separate charge controller. Note since your system is 24v and your panel voltage is 41 you will need a mppt charger else you will lose lots of power generated. Even if you get two more 250w panels you will need another charge controller. |

Cutezt: Well, if your batteries always get around 25% of charge everyday, even on days with significant sunlight, it isn't good. Even normal lead acid batteries will suffer in that condition, not to talk of tubular batteries that even require periodic equalising charging. Your load is probably very small, plus you put it off at night, that is why it looks like they are still performing. Undercharging kills batteries over time due to sulphation. You should do something fast. In my earlier post, I highlighted possible causes of your undercharging situation, and the easiest resolution option you can easily execute with your existing connection and possibly get immediate respite is changing your PWM controller to MPPT. Go that route first and observe whether the charging situation improves (hopefully it does), before you consider the option of increasing your solar array 2 Likes |

Cutezt:I'm just wondering how long you'll continue to turn off your system late at night and what will happen the day you'll sleep off. Adding pv to get your battery to daily float is good but that will not solve this problem. I suggest you work on your night loads and allow the system to run by itself.... When I was using tubular batteries in off-grid system, I managed loads and made sure my consumption at night doesn't go beyond 30% especially in raining seasons and it was very easy for me to refill my battery before evening the following day. I used them for two years and sold out, I was babysitting the batteries as I was hoping to use them for the next 5 years. Today with lifepo4 battery, I'm still waking up the following day with 30% energy consumption, even with my 1hp AC running all through the night and before 12 noon, my battery is fully charged. 2 Likes |
