  1. Looking for any insight on this battery, its used and could have been manufactured 6-8 years ago going by other listings by the same seller. This is substantially cheaper that buy similar battery new. Any advice will be appreciated
  2. Many Thanks for the detailed Post Plonkster, very good point about the micro inverters being on the roof. I ll have a watch of the webinar and rethink my options. Many thanks.
  3. Hi All, I have searched the forum but can seem to find the answer to my question. I am looking to build a new Solar install l for a new property and I am considering using micro inverters as against normal inverters, specifically this one WVC-600 with the aim of maximizing the output from each panel, I ll be looking to install roughly 12 panels at least. I have heard micro inverters tend to last longer up to 20 years as against about 5+/- years for ordinary inverters. So I intend to use backup batteries and the system will not be fed back into the grid, grid will be used when available but nothing going back to the grid. I understand how the setup for a standard inverter setup will work, just need to know how the wiring if a micro inverter is used will look like. My questions are:- 1.) Can I have battery backup if using micro inverters 2.) Do I need a seperate Inverter to actually output the generated power either directly from the Solar panels or from the battery when consumed since the micor inverter will be placed on the roof next to the panels. 3.) Any idea what the setup will look like. Delails of the inverter below, it accept 2x300W panels. cription WVC-600 Solar Micro Inverter Pure Sine Wave Solar Power Inverter 180-260VAC Description: WVC-600 (Wireless Smart) adopts IP65 waterproof streamline design to prevent rainwater from eroding on the surface. Built-in high-performance maximum power point tracking function can better track changes in solar luminosity. And control different output power to effectively grab and collect sunlight. Power transmission adopts reverse AC power transmission technology, which is one of our patented technologies. The power output by the inverter can be preferentially used to provide load, and the endless power can be transmitted to the grid in the reverse direction, and the inverter is used efficiently. The power output, the power transmission rate can reach more than 99%. The communication adopts WIFI to communicate with the mobile phone to point wireless communication mode, and the intelligent monitoring system can collect real-time data of the inverter, and can control the power on/off/power adjustment function of the inverter. Features: - Directly scan QR code and connect with your mobile phone - High performance automatic power point tracking (MPPT) - Reverse power transmission - Intelligent monitoring and management - Input and output are completely isolated to ensure safe use of electricity - High reliability and multiple parallel stacking - Full digital control - Simplify maintenance work (user self-maintenance) - Low operating and maintenance costs - Flexible installation - Wireless communication mode Parameters: Physical Parameters: - Working Temperature: -40 to 60 - Dimensions: 283 x 200 x 41.6mm - N.W.: 1.63kg - Waterproof Level: IP65 - Cooling Way: Self-cooling - Communications Mode: 4G Wireless Communications - Electricity Transmission Mode: Reverse Transmission. Load is in priority - Monitor System: Free - Electromagnetic Compatibility: EN50081.part1, EN50082.part1 - Grid Disturbance: EN61000-3-2 Safety Regulation EN62109 - Grid Detection: DIN VDE 1026 UL1741 - Certificate: CEC, CE National Patent Technology Input Parameters: - Model Number: WVC-600 (Wireless)-230VAC - Maximum Input Power: 2x300W - Compatible Solar Panels: Power 2x300W, Open-circuit Voltage 36V-50VOC - Solar Panel Open-Circuit Voltage Range: 36-50VOC - Peak Power Tracking Voltage: 22-50V - Maximum/Minimum Starting Voltage: 22-50V - Maximum DC Short-circuit Current: 35A - Maximum Input Operating Current: 24A
  4. Hi Again, So Systems has not been fully installed, in my absence a lot has happened. So it turns out the Panels that were installed were infact 150W panels as against the 200W earlier discussed so we currently get about 60-66 VOC. I am not haoppy about this obviously and I have been offered 2 Options, 1. 1. Supplier to extra panels to match the 6 already installed to make it 4 strings each specs more like what below Or Option 2 Take back the panels and refund.. (Ideally preferred but way too much hassle) If taking the extra 2 Panels will be fine, I dont mind really as I can put this down as part of the learning Curve. Any advise will be much appreciated.
  5. Many thanks for your help, so just to clarify, this cannot be used without a separate Solar Charge Controller with my current Flooded battery setup. Option 2 would sarcrifice the Longitivity of prolonging the battery bank. This is still a learning process for me and I would not repeat this when I want to do my own install.
  6. Hi All Again, So installation is currently on going now and the installer engineer has just advised me that the Axpert MKS PLus 3KVA inverter (Hybrid) does not have a built in battery equalizer feature although I have bought the HA02 battery Equalizer/balancer but he insist I need a solar charge controller which will equalize the battery? He said I have 3 Options: 1. Buy another Seperate Invert and seperate Solar charge Controller 2. Use AGM battery instead of FLooded Battery US2200 battery 3 Buy a Seperate MPPT Solar charge controller (This defeats the purpose of going Hydrid) I am in a bit of a pickle . I need advise from the experts. Note: Axpert Manual shows Flooded battery Options Under Battery Settings (default is AGM) could it mean if Flooded is selected there is no need for a seperate equalizer
  7. One more thing guys.. Install is planned for this weekend and there is talking about grounding and Lightning arrestor. Can you knowledgeable people advice on this on this please.
  8. Many thanks for the above, just thinking out loud here..in order to store more energy what if I decided to go down the route of 8x 6v batteries to arcieve my 24V and connect in parallel to achieve 480AH power bank as against 410 bank, how would this affect this calculation and also, is there any drawback in this option as I read somewhere about the point of connecting multiple batteries could be point of failure.
  9. That would be a deal breaker certainly.
  10. That is most certainly kind of you sir! But I am in the UK. Sent from my LG-H850 using Tapatalk
  11. Having looked on eBay here, seems it's quicker and faster to get the mc4 y connectors for now, seems anyone will do is that right? The combiner box I found also came with a 10a fuse, would it be okay to just change the fuse inside the box? Sent from my LG-H850 using Tapatalk
  12. Mine is the one here the Plus Model which support max 1500W array output
