Re: Solar panels in series / parallel

Re: Solar panels in series / parallel

If you get an inverter with two MPPT inputs, they can be at different voltages, or number in series. So one on the east at 8 s, one on the north at 10 s. Yep that would be the ideal solution. Though it seems like pretty limited options in the non-grid tied, budget end hybrid 48v 5kw inverters. Any ...

Solar panels in series / parallel

Hey all, Has anyone got any experience / advice in running used panels in a combination of series and parallel ? I've got an off grid property (no AC available) and I'm looking for a way to maximise the cheap used panels that are readily available. I'm planning to build a 'solar carport' - using the...

Re: Inverter for 48v off grid - PIP xxxxx or something else?

If you are happy with incandescent lights, buy a few packages of 12 volt halogens and put 4 or 5 in series. Ack, how prehistoric :P I think worst case I'd run a seperate step down for LED lighting - but as below it sounds easier just to keep it all standardised. I have a MPP Solar 2424MSE surplus t...

Re: Inverter for 48v off grid - PIP xxxxx or something else?

With panels connected and the inverter switched off, it should wake up each day and charge the battery to the float voltage (make sure it's around 3.36 VPC), and should not boost it to the absorb voltage as long as the idle consumption overnight doesn't reduce the battery voltage much. Idle consump...

Re: Inverter for 48v off grid - PIP xxxxx or something else?

If that is your maximum planned loads, I'd go 12v and use a Projecta IP2000 inverter Battery voltage / configuration isn't really an issue. Are the Projecta's better quality ? Seems like they're around double the price of the MPPT option and limit my peak power by half so I'd be less inclined to go...

Re: Inverter for 48v off grid - PIP xxxxx or something else?

Hi Jay, hope the paddocks are starting to green up after the fires. Got a new shed / dwelling on the way? Hey mate, there's signs of life but regrowth is particularly slow. I had alot of pines where the shed is going and they burn hot and fast so everything is pretty decimated :| Still chasing cont...

Inverter for 48v off grid - PIP xxxxx or something else?

Hey guys, I'm looking for an inverter to use totally off grid. I've done a bit of reading but now I'm more confused by all the model subtleties than when I started! :P My situation is as follows: 48v AVASS battery pack (~20kwhr) 2.5kw solar panels (not adverse to buying more if needed) Totally off g...

Re: Aprilia RS125 electric motorcycle

Thanks - it took a while! I've never actually run it on 21S - that was the plan but the controller is still in the box. I had it up to about 90 with 16S lifepo4 while testing, but that was just *cough* in the back streets so I imagine it had more in it. With nearly double the voltage it'll go faster...

Aprilia RS125 electric motorcycle - SOLD

Hey guys, I REALLY wanted to get this finished and on the road but due to health issues I never had the time to get it done and now with other life demands it has to go. Some may be familiar with this bike - I think it was originally a PhD student project but I've had it now for a little while. It's...
