Hi there, hope you are all doing great guys! Just want to let you know that lithium-ion battery will generally be charging fine over 14V. Preferably, 14.6V , however no issues have seen so far if not exactly 14.6V. Also, you may wonder why alternator can actually charge a lithium-ion battery...
Hey ilia,
A few comments regarding sizing your system.
- A Victron charge controller is too expensive for such an application. There are various other brands that make a decent quality charge controller at a lower price. Indeed, Victron charge controller can communicate with an app, do you...
Hi there, most likely you would need to make 2 string of 4 panels as the charge controller input is usually limited to 150V. And in general, a combination of series and parallel connections is more solid. Add a 250A fuse on the positive terminal of the battery bank.
Ok, I see your panels are 12V each, so then you are fine. However, if one panel is exposed to shade or brakes it will affect the whole string dropping down the power yield up 0. The size of the fuse depends on the largest load that is the inverter. The potential continuous current draw is...
You have a 24V 200Ah battery setup, that is fine as you have a 2400W 24V inverter/solar charger box unit. Locate the fuse just on the positive side. For the best design, add 15A DC breaker between the panels and the charge controller and 80A between the MPPT charge controller and the battery...
Hey Nicko,
What's your area where you are going to use it? It determines the number of panels you would need to offset energy demand. In general, panels should be south-facing at some reasonable angle.
1HP pump seems a lot, 1HP is closely about 750W. In order to start that pump you would need...
Hi folks,
According to your diagram, your 2 x 200W panels are connected in parallel which is fair enough if you have shading, other than that there are no benefits of this setup. However, in order to fully exploit the potential of the MPPT controller, the array voltage should be substantially...
Hi there,
First of all, you indeed can use a 3-string combiner box, like this (https://www.solacity.com/product/midnite-solar-mnpv3/) with 3 x 15 Amp DC breakers. It helps when you need to replace or just turn off the PV side ( it is unsafe to unplug the panels if they are under the load!)...
