What's really worth understanding is that most problems represent as a battery issue, batteries not holding a charge, batteries going flat, batteries not doing what they used to. It would be easy to simply replace the battery bank but that's something we dont do because if the problem isn't fixed it's just going to happen again. We dont replace a battery bank without understanding why the bank failed in the first place and what can be done to stop it happening again.
|SYMPTOM||PROBLEM ||WORK COMPLETED |
|9 Metre Mitsubishi Fuso|
|Batteries flat. Wanted extra solar power to reduce generator useage. Wanted to have better control of power.||Vehicle had good charging capacity but recent mechanical and body work had rendered some components inoperable.||Installed extra 130W solar panel and undertook remedial work to existing panel, upgraded solar regulator, installed battery monitor, replaced the 3 house batteries. Identified phantom loads and other potential probems (eg undersized cabling and no circuit protection). Installed various switches & relays to clear phantom loads. Installed power point. Repaired faulty ignitor in fridge. Taught owner how to properly use existing inverter/charger unit.|
Battery going flat
Insufficient charging due to old, faulty mains charger
|Installed new 3-stage charger, supplied new battery, performed energy audit, supplied LED bulbs, fitted fuse box for circuit protection, wired relay to minimise draw from system monitor, fitted new regulator & brushes to alternator, fixed connections at fuse box for waterpump, found burnt out cable so replaced and fitted relay, installed relay so fridge runs on 12V when engine running, made client aware of consumption V storage so they knew how long they could freedom camp, Heater not going - discovered problem with heater thermostat.|
|Knauss European Cabover Campervan|
Battery going flat
Intermittent, unidentified phantom load and poor monitoring of power consumption
Full check of system, test batteries, look and identify phantom load, installed battery monitor, installed fuses, raise awareness of owner re power consumption and good monitoring of battery.

|Running out of power. Wanted to upgrade solar array (living on board)|
Insufficient power, high draw appliances and inadequate monitoring of power production & consumption.
Installed 3x 130W solar panels, temperature sensor for solar regulator, 150W inverter, 50 Amp 3-stage battery charger, replaced 4 x 6V house batteries. Identified phantom loads and installed switches. Educated owner re use of existing battery monitor and its limitations.
Fridge cutting out, batteries going flat, wanted to reduce power consumption.
|Investigate various power issues and replace 'cranking' batteries which were being used as 'house' batteries|
Install 300Amp Hr deep-cycle 'house' batteries. Upgraded solar regulator to version with a meter. On investigation found various cabling issues and multiple cables terminated at battery post, replaced cabling and installed bus bars. Supplied and installed LED bulbs. Installed switch to fridge for turning off at night. Tidied earth connections throughout vehicle.
|8m 2007 Traillite Motorhome|
|Batteries completely dead after only 18 months of use||Found significant level of ongoing loads were constantly draining batteries and generator wasnt being run for long enough||Constant loads including TV on standby, inverter on standby, alarm system, gas detector added up to around 20Amp hours per day. Customer didnt have a battery monitoring system so was unaware of how significant the loads were and how discharged battery was becoming. When they ran out of power they would run the generator for a few hours so batteries were never being fully recharged. |
We educated customer on the importance of removing loads, understanding battery state of charge and fully charging batteries regularly. Replaced battery bank, supplied LED lighting and installed Digital battery monitoring system
