  2. Thanks for the replies guys. I ended up finding a pump and a panel on bidorbuy for a great price. I’ll report back on how it works once I get it.
  3. Thanks. Yeah I’ve googled ALOT. but I’m not super clued up of what little motors can run on solar direct or not. The solar websites available obviously have them. But sometimes the price negates my electrical bill
  4. Thanks for your reply. Any particular place to look for one?
  5. Hey guys! ive build my own solar heater and I’m using an old copper low pressure geyser as the storage. It works super well- but mounting it to work on thermosyphon alone isn’t easy (still need to keep it out of view). So I want to add a tiny solar inline pump that will turn on when the sun is out and help circulate the water. I can find a number of options at quite a price but I need the most basic system- no switches or anything. Just a pump that can connect directly to a small solar panel and circulate. Thanks for any advise! Peter
  6. Thank you kindly for that reply plonkster! Very informative! I will go with your advise. Last things for now - What size cabling would you suggest from the panel to the batteries via the controller? Obviously the larger the more efficient. I need about 8 m in length. The max out put is around 8amps so will a 15amp wire be adequate? Does it need a fuse? I read a bunch about fuses etc but seems more related to grid tied in units? I have a DB board after the inverter but I want to ensure no burny wires between the panel and the PMW controller If one puts 2 panels in series (or parallel) for that matter - do they have to be the same wattage? Thanks again!!!!
  7. OK so my inverter and batteries are working well! No lights up yet but it runs the booster water pump perfectly. I'm keeping the batteries charged every few days with Eskom and a long extension cord haha. Now I need to buy a solar panel and charge controller and I'm not certain of the specs. My batteries are set up on series so its a 24volt system. Do I need a 24-35 V dc module voltage panel? Or a 12-23V dc one? Does it need to be above or equal to 24 V to be able to charge my batteries in series? There seem to be a lot fewer 24-35V panels on the market. OR - do I get 2 smaller panels and connect them in series? Is that even possible? I'm realizing how little I know now
  8. Thank you for your reply! Good deal is basically free. Paying same as I would for just the 2 batteries so the inverter is free. The reason I didn’t go 12v on the lights is that the distances are quite big- 50 m long building so the higher amp cable comes into the equation. And I guess I need the 220v for the pump anyway
  9. Hey all! My 1st post so please forgive the newbieness..... I have an out building I need to power. really just lights and a water booster pump. 0.37kw pump running prob 15-20 min a day only. Lights estimated 250 (all LED, some tube, some spotlights) watts at any one time. all for about 1 hour a day, and 30 watts all night. Kay thats all pretty easy, but then I got offered a really good deal on an older (but new) cyberpower inverter (CPS2200EI simulated sine wave, 1230 watt unit on a 24 volt system. Its designed for a grid tie in system. I want to hook it up to a solar panel with a PWM controller and 1 or 2 panels 250 odd watt in total. i'll take off the AC input into the inverter and hook up the controller direct to the 12 volt batteries in series. Am I being an idiot? should i rather get the right type of inverter? Is it gonna damage the water booster pump? is the inverter efficient enough? Comments would be massively appreciated! Regards, Peter
