weldted Posted October 7, 2019 Share Posted October 7, 2019 Hi all, I have two Varts 95 amp AGM batteries, what would be the max safe rate of discharge powering a PSW inverter. Not for sustained use but just wondered. Link to comment Share on other sites More sharing options...
spirou Posted October 8, 2019 Share Posted October 8, 2019 The 95Ah capacity rating is probably at the C20 rate of discharge (discharge in 20h), in your case that would be using a 9,5A current. It is considered a medium discharge rate. C10 or fast discharge rating is likely around 80/85Ah and the current for that would be around 16A. C5 (~75Ah? rating) is very fast discharge, in your case probably around 30A but I wouldn't be using that very often if ever. Link to comment Share on other sites More sharing options...
weldted Posted October 9, 2019 Author Share Posted October 9, 2019 Thank you for the reply. This new van is the first I have had with AGM batteries, it only came with one battery and a 100 watt solar panel as standard, and the warranty conditions appear to be broken if anyone other than a Burstner agent puts a hole in the roof. As the cable is too small to carry the current from a second panel increasing the solar will be expensive. Re the inverter I base the demand on using 28 amps @ 12 volt d.c. To produce 1amp @ 230 volts a.c. But only will be using a 300 watt one occasionally. Link to comment Share on other sites More sharing options...
spirou Posted October 13, 2019 Share Posted October 13, 2019 You don't increase current if you wire panels in series and no need for extra holes. But a lot depends on the regulator (can it handle the voltage) https://www.explorist.life/solar-panels-series-vs-parallel/ Link to comment Share on other sites More sharing options...
weldted Posted October 20, 2019 Author Share Posted October 20, 2019 Hi the regulator is 10 amps, so I would suspect 200 watts might be too much on a good day. Link to comment Share on other sites More sharing options...
