woollypigs<p>Mojn, can I pick your brains. We got 300Ah battery but we are finding that it isn't enough for our use in our motorhome aka HQ. We would like to add MORE POWER, but there's not enough space next to the original battery. We got plenty of space elsewhere. Would this be possible to have two "banks" of batteries working as one? (I think about 3-4m cable run is needed, if possible)</p><p><a href="https://sudomakecake.com/tags/SolarPower" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SolarPower</span></a> <a href="https://sudomakecake.com/tags/DIY" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DIY</span></a> <a href="https://sudomakecake.com/tags/Battery" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Battery</span></a> <a href="https://sudomakecake.com/tags/LiFePO4" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LiFePO4</span></a> <a href="https://sudomakecake.com/tags/12v" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>12v</span></a> <a href="https://sudomakecake.com/tags/OffGrid" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OffGrid</span></a> <a href="https://sudomakecake.com/tags/MotorHome" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>MotorHome</span></a></p>

Anomnomnomaly BSC SSC<p><a href="https://beige.party/tags/SolarUpdate" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SolarUpdate</span></a> time again.</p><p>Another not so great month, but a little better than June (which was awful)... yet slightly better than July 2024 (which was also awful)</p><p>Figures are not 100% as the data logging can be from 0-5% out. But it's within a margin of error mostly.</p><p>Generation 524kwh, that's up 18kwh over June, up 54kwh over July 2024... and yet isn't even as good as the generation for April this year... middle of summer and the weather is worse than the start of spring.</p><p>You can see in the yearly graph (image 2) how good the first 5 months of the year were. Then it drops of massively. June 'should' be the highest generation month of the year and yet it's actually only the 4th highest. That's never happened before. It's always been 1st or 2nd... with May beating it in 2023 and 2025.</p><p>That said... we were still effectively off grid for the majority of the month. Only 5 days in the whole month that we imported in excess of 1kwh.</p><p>So we only imported around 26kwh of electric the entire month, whilst exporting 106kwh. Including all daily charges and gas use, subtracting what we earned for export. The bill was £27.04, which meant we increased the credit on the account by a further £72.96 to £862.73. That's just about enough credit to cover the entirety of the winter bills from Nov-Feb (avg between £800-950 for those 4 months).</p><p>As usual the energy company cannot comprehend how solar and batteries work... and think that we should be paying £4.73 a month... whilst predicting that those Nov-Feb bills will be upto £100 lower than they have been every year previously because those Mar-Oct bills are lower thanks to free electric... also thanks to... oh.. I don't know... WARMER weather... we use less gas because the central heating isn't used between May-Sept and only use gas for hot water.</p><p>tl:dr crappy month compared to normal, but crappy is still good and electric was still mostly free.</p><p><a href="https://beige.party/tags/Solar" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Solar</span></a> <br><a href="https://beige.party/tags/Battery" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Battery</span></a> <br><a href="https://beige.party/tags/GoingGreen" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GoingGreen</span></a></p>
