<div dir="ltr">Hi Wrenches,<div><br></div><div>I've got a customer that has an older off-grid system with a 5 string ~2000 Ahr (No I didn't install this) L16 battery bank that is failing. Its a Trace SW 4024 system where the batteries are located in a difficult-to-access crawl space where I'm sure they never got watered.</div><div><br></div><div>We'd like to have these characteristics:</div><div>1. Modular (need to be able to get them to the crawl space)</div><div>2. Maintenance free</div><div>3. Able to be abused and bounce back</div><div>4. Compatible with an Outback MX 60 charge controller (preferably)</div><div>5. In case of charge controller failure, we'd like the batteries to be able to go over the winter with no charge and not be damaged</div><div>6. Need about 30-40 kWh bank size</div><div>7. Able to withstand cool temps (operate decently at 45F) withstand near freezing temps over winter (with no usage)</div><div>8. Price tag isn't a big constraint with these customers</div><div><br></div><div>What are some batteries you might recommend?</div><div><br></div><div>Thanks in advance<br>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div><br></div><div><font color="#305A78" face="'times new roman', serif"><br></font></div><div><br></div>Mac Lewis<br><br><span style="font-family:'Times New Roman';font-size:medium;color:rgb(255,153,0)"><b><font face="Arial, Helvetica, sans-serif" size="3"><p align="left"><font color="#000000" face="Verdana, Arial, Helvetica, sans-serif"><span style="font-size:small"><span style="font-family:arial;font-weight:normal;color:rgb(48,90,120)"><font face="'times new roman', serif">"Yo solo sé que no sé nada." </font><span style="font-weight:700;color:rgb(104,104,104)"><font face="'times new roman', serif">-Sócrates</font></span></span></span></font></p></font></b></span></div>
