    Converting hydro output to battery bank

    Even with the 48v model, I’m sure I’ll still need a step up to achieve the 52-56v requirement for charging. And yes, I’ll call it success if I can achieve 3000Wh. The linear, NPN, NMOS is over my head. I’ll have to consult you guys when I start getting my parts and pieces together.

    Converting hydro output to battery bank

    Very nice. I may have to wait until then. I spoke them before. They seem to be very knowledgeable. Their product and company are out of Greece. Seems like lots of renewable projects in that part of the world

    Converting hydro output to battery bank

    I only have 77’ worth of drop at my site. A comment was posted that the item I’m looking at only had data on its chart of a maximum of 45’. I corrected that comment by commenting that the data was in meters. Maximum head shown is 45 meters. 45 meters is equivalent to 148’

    Converting hydro output to battery bank

    Yes, I’ve considered this several times. If this 248 watts is true with my setup, then there’s nothing else like it, American or Chinese made. I’m sure I could swap the plastic pelton for something more durable. Just so everyone knows, it’s not that I’m trying to go cheap. I called Langston...

    Converting hydro output to battery bank

    This is all in Central America. Anything goes. Only thing that could happen is the neighbor above block that overflow off of his little lake

    Converting hydro output to battery bank

    I’ve checked into the watter buddy before. Not sure if it’s how the alternator is designed, but I could only produce roughly 9 watts with the approximate 30 psi and (1) 4mm nozzle @ 4gpm. This other system I’ve shared is capable of producing 248 watts with my head and flow rate of 2.77gpm...

    Converting hydro output to battery bank

    It’s mostly all on my property. A spring that naturally flows, the rest comes from a little lake further above that’s fed by another spring that drains down on my property.

    Converting hydro output to battery bank

    I’ll contact the manufacturer about this comment, but it may perhaps be able to run on 48v. I’m assuming by the pattern that it’ll produce more than the 24v 200 watts.

    Converting hydro output to battery bank

    I have planned to run through a charge controller. Since my system is already setup with a growatt inverter, I figured I’d just add the same brand charge controller to tie it in together. And hopefully at the same time, it allows for more future expansion with anything else that I want to try...

    Converting hydro output to battery bank

    This is correct that I don’t have the turbine yet. Didn’t know if this setup would be possible. The 48v systems you mentioned, require lots of flow, like 20gpm to make 300-400 watts. During the non-rainy season, I have a constant stream of 5-6gpm. But during this time, my batteries fully...

    Converting hydro output to battery bank

    Thanks for the diagram. It helps to give me a pathway to understanding a little more. But at the same time, please forgive my ignorance. I had my system professionally installed. Works like a dream and customer support is over-the-top for any question I ask. One guy tinkers with the hydro...

    Converting hydro output to battery bank

    Yes, I listed the 24v to 56v step up converter above in my posting. Wouldn’t an MPPT serve as the same purpose as the PWM?

    Converting hydro output to battery bank

    Just checking to see if this is feasible at all. I have a hydro generator in mind that would work as supplemental energy at my site. Checked into Langston and others like it, but I don’t have that amount of flow. The hydro generator is a 24v AC unit. My batteries are 48v DC. I’ve found...

    Pelton to 110v ac?

    I’ve been investigating doing supplement hydro to my solar system. Checking into various 48v dc options. Well I visited my brother-in-laws farm. He got 40’ of head with an unlimited amount of water. His electricity needs are low. So, my mind starts working and of course I’m new to the hydro...

    Adding more panels to charge batteries clarification

    So, I reached out to get answers about this low charge rate. The answer I received is tat because my usage is low that it’ll only charge at 15A each battery for a total of 30A with the 2 battery setup that I have right now. This limited low rate charging is not doing good for me at all. I...

    Adding more panels to charge batteries clarification

    I sent a good day of solar generation. On complete sunny days, we’ll charge to 99% on the batteries. By next morning, we discharge down to about 40-45%. The batteries will fully charge again by 1pm, then by 3pm, we’re making very little on solar. The reason for the additional panels and...

    Adding more panels to charge batteries clarification

    I’ll try to answer the best I can. Panels are actually facing 135* (Southeast) No shading at the house I start getting a charge around 6am. It ramps up pretty quick. Inclination of the panels are approx 20-25%. Temperature around sunrise is 60ish degrees F. Only warms up to 75 degrees all...

    Adding more panels to charge batteries clarification

    Thanks for the clarification. Now I’m clear with a direction of adding another charge controller and more panels. As far as current performance, I just assumed that I was doing good with the charge that I was getting. From what I think you see, it’s not doing well. I don’t know if my...

    Adding more panels to charge batteries clarification

    According to the operating manual, the 6kw unit that I have has a max charge of 60A. I entered the system on the inverter, it’s currently set at a max charge rate of 140A which is the highest it’ll go. The batteries show 100A max charge rate. So, since the inverter will only give 60A, I can...

    Adding more panels to charge batteries clarification

    The max that I’ve seen on a very quick spike has been 4,000 watts. The max on a constant charge has been around 2,600 watts on completely sunny days. Where it usually charges is around 1,500 - 1,800 watts. So, I’m confused again. My current inverter/charge controller has a limitation of...

    So, an 80A 48Vcharge controller with 5,000 watts capacity should do just fine?

    Adding more panels to charge batteries clarification

    Forgive me for my ignorance. When our batteries discharge, it switches to give us electricity from the grid. I guess I assumed that it meant grid tied. We do not send electricity back to the grid by no means.

    Adding more panels to charge batteries clarification

    I think I may try to micro hydro later. Seems like an interesting project especially since I have decent conditions for one. But for now, I think the additional panels should work. We have rain still from the tropical storm that passed over us. I’m currently charging the batteries from the...

    Adding more panels to charge batteries clarification

    For the micro hydro, it’s definitely a possibility for low production. Maybe 300-400 watts max. I have 75’ of drop from 1 site and most likely 100’ from a neighbors site that the overflow flows through my property. Either way, I’d have to invest quite a bit to build a retention and whatever...
