Source and dates: Reconciled against the final Heeler RV Electrical System Owner Reference: What Is Installed (printed page 2), Battery Upgrade (page 3), Future Improvements (page 4), Storage (pages 5–6) and Owner Summary (page 7). The source manual cites equipment nameplates and the OEM wiring diagram. This public URL carries the anonymized summary, not the private manual. Ratings remain documented specifications, not independently repeated tests. The update date is the publication revision date, not an installation or test date. Exact work dates and dated measurement logs are not published here.
Reading the figures below: Equipment ratings describe nominal capability; they are not measured output. The SOC/Ah and 90-day storage-current tables are planning calculations, not results measured on this trailer. Actual capacity, temperature, self-discharge and changing loads affect the outcome.
Who prepared this reference and how Heeler RV assesses a system
1. What is installed
| Component | Make / model | Owner-relevant specification |
|---|---|---|
| House battery bank | Trojan T105-AES | 2 × 6 V, 240 Ah batteries wired in series for 12 V / 240 Ah |
| Converter / charger | Progressive Dynamics PD4560K18NS2B | 60 A; Charge Wizard profile: 14.4 V / 13.6 V / 13.2 V |
| Generator | Cummins Onan 5.5HGJAB-6755L | 5.5 kW; starts from the house battery bank |
| Roof solar panel 1 | Go Power GP-PV-190M | 190 W |
| Roof solar panel 2 | Canadian Solar | Approx. 190 W; exact model not recorded |
| Total roof solar | Two-panel array | Approx. 380 W total |
| Solar charge controller | MC2450N10 MPPT | 50 A; 12/24 V; up to 660 W PV on a 12 V battery system |
| Solar remote display | RM-6 Remote Meter | Displays solar-controller and battery information |
| Trailer control system | BMPRO RVMN101A RVGeniusNode / JAYCOMMAND | Trailer control node |
| Tow-vehicle charging | OEM 7-way charge circuit | Supplemental charging while travelling |
| AC source transfer | OEM automatic transfer system | Selects shore power or generator power |
| Battery monitor on hand | Renogy battery monitor / shunt kit | Not presently installed |
The exterior switch is labelled “Battery Disconnect,” but the OEM wiring diagram shows that it is not a complete battery-bank disconnect. It turns off designated switched loads while several constant battery circuits remain energized.
Owner note: turning the red-key switch OFF does not mean the house batteries are electrically isolated from the trailer. This matters during long-term storage.
2. Completed AGM installation and custom owner’s manual
Heeler RV prepared a custom owner’s manual documenting the installed equipment, charging sources, AGM operation, storage procedure and future improvements. Together with the battery replacement, this is the completed project scope established by the final evidence. The manual is an independent Heeler RV reference, not a factory manual.
Trojan T105-AES battery bank
The original 6 V flooded lead-acid batteries were replaced with two Trojan T105-AES sealed AGM deep-cycle batteries. The bank keeps the trailer's original 12 V architecture while providing a lower-maintenance deep-cycle battery system.
- No routine watering or electrolyte maintenance.
- Designed for repeated deep cycling and partial-state-of-charge use.
- Compatible with conventional AGM charging equipment when the charge profile is set correctly.
How much of the battery should be used?
These batteries can tolerate deeper cycling better than ordinary AGM batteries, but they should not be treated like lithium batteries with a routine 0%-to-100% usable window. Shallower cycling generally supports longer service life.
| Monitor SOC | Approx. Ah remaining | Meaning | Practical action |
|---|---|---|---|
| 100% | 240 Ah | Fully charged | Normal starting point |
| 75% | 180 Ah | Light discharge | No concern |
| 50% | 120 Ah | About half the bank used | Good routine recharge point |
| 30% | 72 Ah | Deep discharge | Recharge soon |
| 20% | 48 Ah | 80% depth of discharge | Treat as practical minimum; recharge promptly |
| 0% | 0 Ah | Fully discharged | Avoid as a normal operating target |
For normal RV use, plan around 50% SOC as a sensible routine recharge point. An occasional deeper discharge is not automatically harmful to Trojan AES AGM batteries, but do not intentionally run the bank below about 20% SOC or leave it deeply discharged.
Converter / charger match
The existing Progressive Dynamics 60 A converter is a practical match for the Trojan bank. Its main charge voltages are close to Trojan's AGM targets, so the converter does not need to be replaced simply because the batteries were upgraded.
| Function | Trojan AES target | Existing PD4560 |
|---|---|---|
| Main / absorption charge | 14.4 V | 14.4 V Boost |
| Float / normal charging | Approx. 13.5 V | 13.6 V Normal |
| Long-term maintenance | Low maintenance voltage | 13.2 V Storage |
Solar controller profile
The MC2450N10 controller should be checked for the Trojan AGM bank. A suitable user-defined profile uses about 14.4 V boost/absorption, about 13.5 V float, and automatic equalization OFF. Confirm current manufacturer guidance before changing settings.
3. Logical future improvements
Before adding equipment, first identify the actual limitation: not enough stored energy, not enough charging, or a need for more 120 V power.
- Install the battery monitor / shunt. A correctly configured shunt sees current entering and leaving the whole battery bank and provides a much better fuel-gauge view than solar-controller information alone.
- Add a proper solar disconnect. A clearly labelled, properly DC-rated 2-pole PV disconnect on the solar-input side of the MC2450N10 improves serviceability and storage testing.
- Add solar if charging recovery is the problem. The existing array is about 380 W and the controller is rated for up to 660 W on a 12 V system. Additional panel capacity is possible subject to confirming panel compatibility, wiring and protection.
- Add battery capacity if stored energy is the problem. A second matched pair of T105-AES batteries could increase the bank to approximately 12 V / 480 Ah. Additional batteries are best planned while the original pair is still relatively new.
- Add an inverter only for a defined 120 V need. Significant inverter loads should be planned together with battery capacity, conductor size and overcurrent protection.
4. Long-term storage procedure
Because the red-key switch does not fully disconnect the battery bank, long-term storage should include an actual current check rather than assuming the batteries are isolated.
Plug the trailer into shore power and allow the Progressive Dynamics converter to complete the charge. Overnight or about 24 hours is a practical preparation period. The goal is a fully charged bank, not simply a fixed number of hours.
Unplug shore power, disconnect the tow vehicle and make sure the generator is off. Solar must also be removed from the test. Use a proper PV disconnect if installed, otherwise perform the current test after dark or safely isolate the identified PV circuit.
Use the trailer's normal storage-switch position. Remember that constant B+ circuits remain connected even with this switch off.
Wait about 5 minutes so control modules can enter their normal standby state.
Preferred method: read a correctly installed shunt. Alternate method: use a low-current-capable DC clamp meter at an appropriate series-bank conductor where no midpoint loads are present.
For storage lasting several months, check battery condition periodically. Trojan guidance should be consulted for the current recharge threshold and storage interval. Do not assume solar is maintaining the bank unless solar operation has been verified.
Storage-current guide
| Continuous draw | Use in 90 days | Owner guidance |
|---|---|---|
| 5 mA | 10.8 Ah | Excellent |
| 10 mA | 21.6 Ah | Very good |
| 20 mA | 43.2 Ah | Investigate if practical |
| 50 mA | 108 Ah | Too high for unattended long-term storage |
Target: storage current should be as close to zero as practical. Around 10 mA or less is excellent. If measured draw is above about 20 mA, identify what remains energized before leaving the trailer for several months.
Storage SOC checkpoints
| Approx. SOC | Rested 12 V bank voltage | Meaning |
|---|---|---|
| 100% | 12.84 V | Fully charged |
| 75% | 12.54 V | Recharge point during storage |
| 50% | 12.24 V | Too low to leave sitting |
| 20% | Approx. 11.9 V region | Deeply discharged - recharge promptly |
Voltage-based SOC should be checked after the batteries have rested with charging and significant loads removed. A correctly configured shunt is the better day-to-day SOC indicator.
Owner summary
This trailer uses a 12 V / 240 Ah Trojan AES AGM house bank supported by a 60 A Progressive Dynamics converter, approximately 380 W of rooftop solar, the existing 50 A MPPT controller, the Onan generator and supplemental tow-vehicle charging. It can remain a conventional AGM system and still provide a capable, serviceable RV power setup.
- Best first improvement: install and configure the battery monitor / shunt.
- Best serviceability improvement: add a proper PV solar disconnect.
- Add solar if recharge time is the limitation.
- Add another matched Trojan pair if stored energy is the limitation.
- Consider an inverter only when there is a defined off-grid 120 V requirement.
Future changes should be checked against the actual equipment, conductor sizes, fuse/breaker protection, battery condition and installation layout present at the time of the work.
