ceaser: Hi Ceaser and everyone. I have an idea am trying to figure out it's possibility before embarking. Please would appreciate a response accordingly. See questions below: 1. In a complete setting of inverter, mppt controller, batteries and solar. I want to replace the solar panel with an equivalent battery charger voltage. Example, on the mppt, the batter is connected to the battery slot, inverter is connected to the inverter slot then instead of the solar, I will connect an equivalent voltage capacity say 24v battery charger for a 24v inverter system. (normal AC-DC battery charger) to the mppt. I already have my idea sketched waiting execution. Guys, your thoughts please. 2. We all know on the mppt, the solar slot only allows for a ONE-WAY current flow, the battery side allows for a TWO-WAY current flow. What is the nature of flow on the inverter/load side. This is just to enhance my knowledge to fine tune my concept/idea for my new concept. |

contease: Whatever you want to do, do not connect any form of charging source apart from solar panels to the solar panel input of a charge controller. The charge controller is for panels, not for AC chargers. You can't even connect wind turbine generator to the terminal except manufacturer's specification says the charge controller also supports wind power input. contease:The solar input terminal does not "allow two way flow" as you think. Rather the design is to prevent current flow in the reverse direction from the battery going back into the solar panel at night. This has two benefits: it prevents parasitic drain from the batteries into the panels at night and it also protects the solar panels from damage that may result from that. contease: The load terminals of a charge controller also has reverse protection, especially the premium ones, and usually supports the max current of the CC itself, that is a 60A charge controller may support loads up to 60A on the loads terminals. That notwithstanding, it is not usually used for inverter loads. It's just for light loads like DC appliances like your DC bulbs, modems, chargers etc. So discard the idea of hooking your inverter onto the load terminal of your CC. Rather connect it directly to your battery terminals. 1 Like |

@ contease 1. You can connect your proposed battery charger to the DC bus ![]() The bus bar on the left carries the batteries, then all your dc loads (Inverter(s), CC, "your proposed dc charger" etc) are on the right bus bar. 2. Yes, you can connect a different DC source to the charge controller PV input to deceive it. As long as you don't exceed its maximum input current limit and voltage. 3. Post it here. contease: 1 Like |
Re: Solar Energy, A Complement To FTA by Barezzi(m): 9:47am On Sep 15, 2020 |
I plan to do something similar on my genset starter battery (12Vdc 7Ah) to keep it healthy and charged as it runs once a quarter. Options: A. Get a Victron Orion 48v to 12v DC/DC converter and a timer to switch it on twice a month for 30 mins B. Get an old laptop charger and connect it to the pv input of a charge controller. The same timer will switch on the laptop charger as above. C. Replace the genset starter battery with Lithium equivalent and charge once a year. D. Replace the timer switch above with a Victron BMV 712 from ojeysky and switch based on SOC or voltage. E. ![]() Any more suggestions will be appreciated. |

Barezzi: Barezzi, Many Thanks for ur kind suggestion, but this will make for a Manual switching, if yes then won't be a good one for a time when there will be nobody to switch.. But if no, then the cost implication will return the whole idea to same cost of using panels right. 2. Well, its a 12v/24v ordinary batter ac-dc charger while the mppt will be a 24v/48v... 3. ![]() ![]() |

You want Oga Barezzi to spend 100k plus on a BMV to keep a max 20k battery topped off? Perhaps since Grid and PV are always available connecting a suitable AC/DC converter (laptop charger) to the PV input of a PWM CC to keep the battery always charged is the leanest option. You basically want to max out existing resources and the incremental energy needed to keep the starter battery topped off is negligible so it can be on 24/7. Odds are good that everyone has a 19.xxvolt laptop charger + el cheapo PWM CC sitting around unused and happy to be commissioned for this task. There are even purpose built small wattage panels + PWM CC to perform battery maintenance but a custom solution is more reliable and stable I believe. ojeysky: Barezzi: 2 Likes |
Re: Solar Energy, A Complement To FTA by Barezzi(m): 11:19am On Sep 15, 2020 |
Thanks Niyi and ojeysky ![]() Option B it is then. I already have old laptop chargers lying around, so what i need now is a cheap weather proof IP65 PWM CC. NiyiOmoIyunade: |

Abdomox: Epsolar 60amps mppt Morningstar mppt. Victron mppt. Fangpusun wch is a chinese victron clone has that capability, but you need a special usb cable to unlock it. Another option is buy an inverter with equalization option. Mustpower,sorotec, phocos all have these. Note these are just the models i can remember now There are other models with similar capability out there 3 Likes |

So when I got introduced to Sonoff I was hoping the hub version would work for my household and ordered it, unfortunately based on my house wiring and the various dependencies thereof, the individual Sonoff basic is what will work for me. My AliExpress tracking says the hub is now in naija while the basic pack I ordered is still no where to be found(hoping it will arrive soon as well) Interested in the hub? You can book it for 22k. It's the R3 version with 8kw+ cumulative capacity. It will come with a remote as well
